How to solve problem when setup says AutoCAD is installed

Have you run into a problem when the installer says on Configure Installation that AutoCAD is already installed and trying to clear out remaining folders, files and registry keys does not help? AutoCAD is not installed but still the setup says it is. It might be that you had tried to manually uninstall AutoCAD (or Revit or whatever it is) and failed to do it 100%. What to do?

This trick might help to solve the problem. Note that the GUID (the code at the end in italics) is different for different applications and versions so you might need to search in the parent folder or go through them all to find what you look for.

Locate this folder and delete it with its content. Make a backup if you want to be on the safe side.

Use regedit, locate this registry key and delete it with its content. Make a backup if you want to be on the safe side.

After that hopefully you will find that you can run the setup and install AutoCAD or whatever product you had in mind to install. Now you know how to install AutoCAD even if AutoCAD is already installed even though it was just the installer thinking so.

Jumping Cursor and performance issues in AutoCAD

Cursor performance issues in Windows 7 when hardware acceleration is off is described in this new knowledge base document from Autodesk.

You are running AutoCAD 2010 up to AutoCAD 2013, AutoCAD LT or an AutoCAD-based vertical product in Windows 7 and are experiencing cursor performance issues or the cursor is jumping as if SNAP was enabled.

This issue only happens in Windows 7 and affects AutoCAD LT and all AutoCAD-based products where hardware acceleration has been turned off.

Enable Hardware Acceleration if possible. Use 3DCONFIG. Another method is to disable Aero effects on Windows 7. It is also recommended to in AutoCAD, turn off all Dynamic Input features, including dynamic prompts, by setting the DYNMODE system variable to 0. Full details are found here: TS14898223

Autodesk to cease support of Windows Vista

Still using Windows Vista? If you plan on using Autodesk 2013 products on Vista read this:

Microsoft Windows Vista Support FAQ by Autodesk

Beginning January 1, 2012, Autodesk will have formally ceased support of the Microsoft Windows Vista Operating System for all new (and upgraded versions) of its products and services released in 2012.

Currently shipping versions and previous versions of our software (delivered prior to January 1, 2012) will continue to be supported on this operating system.

Why is Autodesk ending support for Windows Vista in 2012?

Microsoft ended sales support for Vista in 2011, and will end mainstream support in 2012. Our research and customer engagement on this topic has shown that an overwhelming majority of our installed base has already moved off of this operating system. Customers looking to upgrade their hardware and operating system have indicated Microsoft Vista is not a viable option given the availability of Windows 7.

UPDATE: A week after this post Microsoft extended support for Vista. ref Will Autodesk follow?

Where can I find information on Microsoft’s planned support for its Operating Systems?

You can find information on Microsoft’s Windows lifecycle (both sales and support) here:

Why are you ending support for Windows Vista when XP, an older operating system, is still supported?

Through Autodesk’s research and customer engagement, there is still a large population of customers utilizing this Operating System in their work environments. We will work with our customers in the coming 12-24 months to understand their transition plans and make a support decision about Windows XP when it is appropriate to do so.

If I upgrade my Windows Vista computer to Windows 7, will my existing 2012 licensed products still work?

If you are intending to upgrade your Operating System, it is recommended that you reinstall your Autodesk products once that upgrade is complete. Your existing product license is still a valid, but the product will need a new authorization code to work with the new operating system once installed.

If I choose to buy a new computer with Windows 7, can I reinstall my 2012 products on the new computer or will I have to buy new licenses?

Yes, you can continue to use your current Autodesk products with this new operating system. Once installed, you will have to obtain a new authorization code.

How do I migrate my older licensed Autodesk products to a Windows 7 computer? I lost the install discs and serial numbers a while ago.

Please contact the reseller or company where you originally purchased the Autodesk software for a copy of the product and your original serial number. If you are on Autodesk Subscription you can just go to the Subscription website and access the previous three versions of the product.

When will Autodesk support Windows 8?

Depending on Microsoft’s own release schedule for this new operating system, Autodesk will test its product line with Windows 8 and release a support statement when it is appropriate to do so.

Will the Autodesk software/application I recently purchased (i.e. 2012 version) work on Windows Vista even though Autodesk is ceasing support for this Operating System?

Yes, the current Autodesk product line (version 2012) will continue to be supported on Microsoft Vista. Support will cease for new versions of Autodesk products released beginning January 1, 2012.

How does this ‘ending support’ affect me and the products that I currently own (version 2012 and earlier)? I am still on Windows Vista and do not have the ability to migrate to other Windows OS.

Autodesk will continue to support you and your existing, purchased products on Windows Vista in alignment with our current product support policies.

What do I do if I run into issues with Autodesk products on Windows Vista? Who do I contact for support?

You can continue to utilize your existing Autodesk support channels for Windows Vista issues for Autodesk products/versions which have shipped prior to January 1, 2012. For new versions of Autodesk software shipping after this date, please refer to the Autodesk Discussion Forums for peer-to-peer support if you decide to install these Autodesk products on the Windows Vista operating system.

I’m running Microsoft Vista with my Autodesk Products – can I still purchase apps and plug-in’s from Autodesk Exchange beyond January 1, 2012?

If you are installing apps from Autodesk Exchange, please check with the supplier/developer of the app for system and product requirements pertaining to Microsoft Vista support for your particular Autodesk product(s).

How to remove all Autodesk products from Windows

Sometimes this is needed. I’ve done it many times both on my machines and on users machines.

How to remove all Autodesk products from a Windows system

From Autodesk’s Knowledge base: TS45252


A previous attempt to install or uninstall an Autodesk® product failed to successfully complete and now you are unable to install or reinstall an Autodesk product on your system.


In these cases, it is strongly recommended that you clean your system by uninstalling all Autodesk products and supporting applications (add-ins, utilities, enablers, etc.), and by removing related files and settings before attempting to reinstall. The end result is a clean system on which you can install your new Autodesk product.

Before you begin
  • These procedures are intended to completely remove Autodesk products and related support files from your computer including customization files such as menus, AutoLISP, PGP files, etc. If you wish to preserve any existing customization, you must manually back up those files before executing the procedures that follow.
  • Before you starting uninstalling your Autodesk products, we recommend you restart your system to ensure that any pending Windows OS updates get applied first.
  • Some options are presented differently depending on the version of Windows you are running. The following procedures include descriptions for the Windows® 7, Windows Vista®, and Windows XP operating systems. Follow the appropriate  instructions for your operating system.

For most Windows-based Autodesk products, the process of uninstallation is handled through the Windows Control Panel:

  1. From the Windows Start menu, open the Control Panel.
  2. Select “Uninstall a program” (Windows 7/Windows Vista) or “Add or Remove Programs” (Windows XP).

Windows 7 / Window Vista

Windows XP

The first thing to note is that each Autodesk product is listed separately and must be uninstalled separately.

List of installed applications

Even though you may have installed all of the products in a suite in a single installation, each individual Autodesk product and related add-in, enabler, bonus pack, or other supporting application must be uninstalled separately.

Uninstall peripheral applications

If you're going to uninstall a product, you should uninstall the related peripheral applications before uninstalling the main application. For example: if you're going to uninstall 3DS Max Design, you should first uninstall the FBX add-in for 3DS Max Design. Uninstall this and any other related add-ins and then uninstall the main applications. This also applies to modules such as the VBA enabler, Subscription Advantage packs, and Autodesk material libraries.

Note: When uninstalling the Autodesk material libraries it’s important to remember that these libraries are shared across all Autodesk products and should not be removed unless you are removing all Autodesk products from the system.

  1. Select the product to be uninstalled and click the “Uninstall/Change” link (Windows 7/Windows Vista) or the “Change/Remove” button(Windows XP).
  2. In most cases this will launch an uninstaller for the selected component, allowing you to uninstall it from the system.

Repeat this process for all add-ins and supporting applications before beginning uninstall of the main Autodesk products.

When uninstalling the material libraries, it's best to uninstall from largest to smallest. Begin by uninstalling the medium resolution image library–assuming that library is installed on your system–followed by the base resolution image library, and then the Autodesk material library.

Uninstall Autodesk products

Once you have uninstalled all peripheral applications, you can begin uninstalling the main Autodesk products:

  1. Select the product to be uninstalled and click the “Uninstall/Change” link (Windows 7/Windows Vista) or the “Change/Remove” button(Windows XP).
  2. At this point, the Autodesk installer will open in maintenance mode offering you the options to: Add or Remove Features, Repair or Reinstall, or Uninstall the selected product. 

    AutoCAD 2011 installer in Maintenance Mode
  3. Click the Uninstall option and click Next to confirm that you want to remove the product from your computer (if you are prompted to remove shared files, click Yes to All).
  4. After the Uninstall is complete, click Finish to close the installer.

Repeat steps 1-3 for each Autodesk product to be uninstalled.

Note: The uninstall procedure for some Autodesk products may require you to restart the computer when the uninstall has completed. If this is the case, restart the computer as instructed, return to the Control Panel and continue removing any remaining Autodesk products.

Delete remaining Autodesk product files and folders

Warning: The following steps instruct you to delete folders at locations that would affect all installed Autodesk products. These steps assume you have previously uninstalled all Autodesk products and related peripherals and that it is safe to remove those folders.

1. Using Windows Explorer, locate and delete the installation folder for each Autodesk product that was uninstalled in the previous procedures, e.g.,  "C:\Program Files\AutoCAD 2010" or "C:\Program Files\Autodesk\AutoCAD 2012".

2. Delete the folder, "C:\Program Files\Common Files\Autodesk Shared"
Note: These locations may be different if your OS is configured to store the Program Files folder on a drive other than C: or if you installed your Autodesk product to another drive and folder name.

3. Delete the following user profile folders (substitute your login name for %username%):

Windows 7/Windows Vista

  • C:\Users\%username%\AppData\Roaming\Autodesk
  • C:\Users\%username%\AppData\Local\Autodesk
  • C:\ProgramData\Autodesk

Windows XP

  • C:\Documents and Settings\%username%\ Application Data\Autodesk
  • C:\Documents and Settings\%username%\Local Settings\Application Data\Autodesk
  • C:\Documents and Settings\All Users\Application Data\Autodesk

Windows 7 and Windows Vista: Depending on your system settings, Windows Explorer may not automatically display all the subfolders under the Users folder. If you cannot locate these folders by navigating to the folder, copy and paste the above folder locations into the Windows Explorer address bar.

Windows Explorer address bar

Delete remaining Autodesk product entries from the Windows registry

Warning: Improperly editing the Windows registry could render your operating system unusable. Microsoft provides a wealth of critical information that you need to know about the registry in the Microsoft Knowledge Base at

Use the Microsoft® Registry Editor at your own risk and only after backing up the registry. Instructions on backing up your registry can be found in the following Microsoft Knowledge Base articles:

Additional information about the registry is available in the Help topics in the Microsoft Registry Editor.

  1. Log on to the workstation as a member of the local Administrators group.
  2. Launch the Run dialog by typing [Windows key] + R (Windows 7/Windows Vista) or clicking Start > Run (Windows XP).
  3. In the Run dialog, enter REGEDIT in the “Open” edit field and click OK.
  4. In the Registry Editor, locate and delete the following subkeys:
    - HKEY_CURRENT_USER\Software\Autodesk
    - HKEY_LOCAL_MACHINE\Software\Autodesk 

    Deleting a subkey in the Registry Editor
  5. Close the Registry Editor.
  6. Restart the computer.

Before reinstalling any Autodesk products

At this point, each of the previously installed Autodesk products—along with residual files, folders, and registry settings—should now be gone from the system and you are almost ready to start installing (or reinstalling) your Autodesk products. Before you begin, we recommend you perform the following tasks to help ensure a successful installation:

  1. Reboot your computer. You should really do this even if you have not been prompted to reboot. Restarting your system before installation helps ensure that any pending Windows OS updates get applied before you starting installing your Autodesk products.
  2. In Windows Explorer, delete the contents of your Windows Temp folder, but do not delete the Windows Temp folder itself. You can locate the Temp folder by entering %TEMP% in the Address bar of Windows Explorer.
  3. Close all running applications. Some applications—Microsoft Outlook, for example—can interfere with the installation process. So, before you begin installing, it's just a good idea to shut down other applications that are running.
  4. Disable any virus-checking software running on your system. Virus-checking applications may block certain activities detected as suspicious, e.g., accessing the registry or adding/removing/updating DLL files, even though these activities are common when installing or removing programs. Not only can it slow down the installation process, but it can actually introduce corruption. So make sure that your virus checking software is turned off before you install, and make sure you turn it back on when you're complete.

Several anti-virus programs can be disabled by right-clicking its system tray icon and selecting Disable from the shortcut menu (for more information about disabling your anti-virus software, refer to the vendor of that software). In some cases, disabling the anti-virus application from the system tray may not be sufficient and it may be necessary to use the task manager to end the process for the anti-virus software that is still running.

To verify that an anti-virus program is not still running in the background:

  1. Press [Ctrl] + [Alt] + [Delete].
  2. Click Task Manager.
  3. On the Processes tab of the Task Manager, select the process for the anti-virus program and then click “End Process”.

You are now ready to install your new Autodesk products on the clean system.

Office 2010 Service Pack 1 Error 0x8024002D

Office 2010 Service Pack 1 (SP1) is now available and when I installed it via Windows Update I got the error 0x8024002D. First time it just failed to install. I then tried again and got a dialog box asking for an MSI file so I browsed for it. Still it didn’t work so I tried again and got asked about another MSI file. After a few tries it finally worked out. Problem solved.

(Checking the log file in %TEMP% I saw this: Error 1706. Setup cannot find the required files.  Check your connection to the network, or CD-ROM drive.    For other potential solutions to this problem, see SETUP.CHM.")

Strange that the files could not be found because they were available. I had them on an external hard drive, maybe that confused the installer.

This KB article might otherwise help.

On the topic I found that I had to rebuild the whole Index, something I’m not so happy about.

Here are some highlights of SP1:

Excel 2010 SP1 Improves the overall stability, performance and backward compatibility with earlier versions by addressing bugs that affect lots of users.

Outlook 2010 SP1 includes Office 365 support.

Outlook 2010 SP1 can be set to always use the default sending account.

Outlook 2010 SP1 Fixes an issue in which the snooze time does not between appointments.

PowerPoint 2010 SP1 The default behavior for the Use Presenter View option is changed to display the slide show on the secondary monitor, and display the notes on the primary monitor.

For complete list of improvements see this KB article including details for Word 2010 SP1 and OneNote 2010 SP1.

.NET code problem on Windows Server 2003 solved

I spent several hours hunting down a problem a customer had with JTB FlexReport on Windows Server 2003 SP2. The solution was in the end a single row. Things worked fine on Windows XP, Windows Vista, Windows Server 2008, Windows Server 2008 SP2  and Windows 7, but for some reason it failed on Windows Server 2003.

In the code I narrowed down that this call failed but I could not figure out why:

Database db = DatabaseFactory.CreateDatabase();

I got this error using Microsoft Enterprise Library 2.0:

Object reference not set to an instance of an object.

I was wondering if it had to do with the Enterprise Library version but I got this error using Microsoft Enterprise Library 5.0:

Activation error occured while trying to get instance of type Database, key ""

I then wondered if the problem was that I had one .exe made by VB.NET and a DLL made by C#, or that it was running as a Windows Service, or that some code had been upgraded all the way from VB6 etc.

Eventually I was able to scale away a copy of my program to just a few rows and still had the problem. Then I created a similar program from scratch and got it running. I could then start to compare the two file by file using DiffMerge and eventually I was able to find that in app.manifest I had to add the following:

<assemblyIdentity version="" name=""/>

just before <trustInfo

Now that I found the solution I looked up more details and found that reading any configuration settings from the applications .config file is not working. I also found that it actually is due to a bug in Windows Server 2003. Calls to System.Configuration.ConfigurationManager.AppSettings return null. In Windows Server 2003, if the application has the following SxS manifest, then CLR will not use the application config file even if it exists. This bug does not exist in Windows XP, Windows Vista or Windows 7. Application config file is not used if the application has certain SxS manifest and Lesson Learned: Missing language attribute in ‘assemblyidentity’ element can cause SxS (SideBySide) application loading failure on Windows XP and Server 2003

DPI scaling issue with AutoCAD 2012

2012: AutoCAD framework issues when running at high DPI scaling


You are running an Autodesk 2012 product on a system whose screen resolution is scaled to 150% and you are seeing abnormalities in the standard buttons and ribbon controls including:

  • A detached and floating red A (upper left corner)
  • The X button to close AutoCAD (upper right corner) does not work
  • Many ribbon controls do not perform as expected


Autodesk 2012 products may exhibit these issues on systems where the screen scaling is set to 150%. You can work around this by setting the screen resolution of your system to 96 DPI (or 100%).

An alternative method is to right-click on the AutoCAD icon, select the Properties settings, and select the option to "Disable display scaling on high DPI settings."

(When I tried this the Compatibility Settings where disabled and grayed out. I found that this only works for 32-bit programs and not for 64-bit programs. Too bad.)

How to start a new process de-elevated after installation

I was trying to launch an application at the end of an installation I’ve created with Visual Studio. My problem was that the installation is running with elevated privileges as administrator (UAC) and I want the application to run as a normal user.

One problem with the application that was launched by the installer was that when reading and writing to the registry it ended up at HKEY_USERS\.DEFAULT instead of HKEY_CURRENT_USER. I noticed that the process was run by NT AUTHORITY\SYSTEM instead of the expected COMPUTERNAME\USERNAME. This will also cause problems if you want to open a webpage after the installation and there is no current Web Browser running.

I knew how to elevate the process using the verb runas.

p.StartInfo.UseShellExecute = true; p.StartInfo.Verb = "runas";

But I could not find any way to use the verb to de-elevate. I searched for a solution online but could only find convoluted ways like using CreateProcessAsUserW, Code Injection in the shell process or using the task scheduler to register a task to run as the currently logged on desktop user.

I found this post and tried using the User Account Control Helpers to no avail for some reason.

Process p = UacHelpers.UserAccountControl.CreateProcessAsStandardUser("notepad.exe", "");

Eventually I came up with this simple C# code thinking it might do the trick. It actually runs the new program with reduced permissions but not as the intended user. This could be useful in other situations though.

Process p = new Process(); p.StartInfo.FileName = "runas.exe"; p.StartInfo.WindowStyle = ProcessWindowStyle.Normal; p.StartInfo.Arguments = "/trustlevel:0x20000 notepad.exe"; p.Start();

Unfortunately it didn’t help me here.

I then turned back to the UacHelpers source code and commented out these rows because I noticed that the process was not really elevated from the start so I did not want the simple way to start the process.

//if (!IsCurrentProcessElevated) //{ // return Process::Start(exePath, arguments); //}

Using this trick it was possible to have an application like my setup that runs with administrator privileges (thanks to UAC) to start another process with standard user privileges and as the expected user.

Please comment if this helps you or if you have any related suggestions on better approach.

WebP vs JPEG vs JPEG 2000 vs JPEG XR

Image compression is on the news again and this time it is Google behind it trying to dethrone the lossy format JPEG. Google does not mention JPEG XR (aka Windows Media Photo and HD Photo and with file extension .WDP or .JXR) that is natively supported by Windows Vista, Windows 7 and Internet Explorer 9. JPEG XR still have not gained any real usage after several years. Could it be licensing issues behind it. Let’s wait a few years and see if Google can get JPEG replaced. In near future WebP will be supported by Google’s Chrome browser and all of this .

compression vs alt

WebP is a method of lossy compression that can be used on photographic images. The degree of compression is adjustable so a user can choose the trade-off between file size and image quality. WebP typically achieves an average of 39% more compression than JPEG and JPEG 2000, without loss of image quality. Alpha channel support is planned for.


I wish that a future Windows Live Writer had a choice to optimize the image when publishing so you could chose the best format for the purpose. Something like this already exists in Microsoft Expression Web.

Another wish is that Snagit could respect the image format setting when copying directly to clipboard or the preview editor. Now all is PNG.

Below is one JPEG XR image that should be possible to view in IE9.

Update. The first image below cannot be viewed in the first public IE9 beta for some reason even though it can be seen in Windows 7. It might have to do with some that it was saved with a quite old HD Photo plugin for Paint.NET.


So I added one that works for sure in IE9 beta.

Remove items from Windows Control Panel

Have you ever wanted to delete or hide items from Windows Control Panel? Under Hardware and Sound in Windows 7 I find for example Autodesk Plot Style Manager and Autodesk Plotter Manager that are added after installing AutoCAD.


Delete or move these files and reopen the Control panel and the items are gone.


You can also hide items using the Registry editor or Group Policy Editor (look for Hide specified Control Panel items and List of disallowed Control Panel items) as it is easier if you want to do it on many computers and some items cannot easily be deleted like the two in the example above.

Virtual memory monitor gadget for AutoCAD

Autodesk releases its first Windows gadget.

Use the Autodesk Performance Monitor to gauge the virtual memory utilized by running versions of AutoCAD and AutoCAD-based vertical products.

The Performance Monitor is a Windows desktop gadget that provides a color-coded status bar indicating the level of usage of virtual memory by AutoCAD products (AutoCAD 2009-2011 and some verticals). When large amounts of virtual memory are in use, the running process may become unstable.

For obvious reasons this will only work on Vista and Windows 7 systems.

Free Download of Performance Monitor for AutoCAD via Autodesk Labs (in a limited number of countries)

Test comments:

The location after installing the gadget was half way outside the screen.

Using the Close drawing button did close the drawing but put AutoCAD in a Not Responding state.

New functionality and performance improvements for the graphics platform in Windows 7

An update is available for Windows 7 and for Windows Server 2008 R2 which provides new functionality and performance improvements for the graphics platform. Get the update KB2028560 here.

I tried to install it but not sure how much is improved but give it a try. I found some mentioning that it might be a requirement for IE9 (Internet Explorer 9). It will probably come via Windows Update later on if needed.

“Judging by the information shared by Microsoft, the performance and functionality boost update for Windows 7 is designed to kick up a notch key APIs (application programming interfaces) of DirectX 11.
The Redmond company mentions such APIs as Direct2D, DirectWrite, Direct3D 10.1, and DirectX Warp.” - Softipedia

Licensing error 1.5.-15 in Network License Manager

When you started the network version of AutoCAD 2009 or AutoCAD 2010 on a Microsoft Windows Vista or Windows 7 workstation, you received licensing error 1.5.-15.

Basically the solution is to open Local Area Connection Properties dialog box and clear the "Internet Protocol Version 6 (TCP/IPv6)" check box. Hopefully a better solution will come as IPv6 might be needed eventually.

Knowledge Base document has all details: Licensing error 1.5.-15 when running the Network License Manager on Microsoft Windows Vista or Windows 7

Here is another identical error but another solution: AutoCAD 2007 network license manager Error 1.5.-15

Speed up Windows 7 logon with 30 seconds

Consider the following scenario:

  • You have a computer that is running windows 7 or Windows Server 2008 R2.
  • You set a solid color as the desktop background.
  • The Desktop Window Manager Session Manager service is running.
  • You log on to the computer locally.
In this scenario, the Welcome screen is displayed for 30 seconds during the logon process.

See details in this hotfix or just change the background to using a picture that can be a solid color.
