If you use a Macrovision FLEXlm/FLEXnet-enabled application and there are problems to pull the network license it might help to use the FLEXLM_TIMEOUT environment variable (has to be added) on the computer that has trouble getting the license. The user might get the dialog box (FLEXlm License Finder dialog box/FLEXnet License Finder dialog box) asking about specifying the location of the license file or license server. Typically this happens when you use a slow dial-up connection but also with a high speed broadband connection it can happen or if you have a network with servers in different countries or far from each other, Autodesk GNUL licenses or the like. In the case of AutoCAD it has been a typical thing needed to do introduced with AutoCAD 2007 and later. Try a value like 1,000,000 as a start and use higher if needed.
FLEXLM_TIMEOUT is only working on a Windows PC. Sets the timeout value a FLEXenabled application uses when attempting to connect to a license server system port in the range 27000–27009.
Values are in microseconds, within the range 0–2,147,483,647. The default setting is 100,000 microseconds.

When you launched AutoCAD 2009 as a non-administrative user using Windows Vista 64-bit, the FLEXlm License Finder dialog box did not display.
This issue occurs because the license server path information points to the HKLM\Software\Wow6432Node, which is not accessible to non-administrative users.
To resolve this issue, redirect the license server path information to HKLM\ Software \FLEXlm License Manager.
Knowledge Base document for more information if you get the following: Your application was not able to obtain a license because the FLEXlm license manager could not determine where to find the licensing data it needs. Please choose one of the following:
Specify the License Server | Specify the License File
FLEXlm® License Finder dialog box is always displayed at startup
