Autodesk will continue to “unofficially” support VBA in its 2012 products, thus VBA (Visual Basic for Applications) is still available and as a separate installer.
The Express Tools command REVERT still requires VBA.
Trying to click on Installation Help, System Requirements or Readme does not work.
At least the actual installation works. If you have AutoCAD 2012 verticals like AutoCAD Architecture 2012, AutoCAD MEP 2012, AutoCAD Electrical 2012, AutoCAD Map 3D 2012, and AutoCAD Mechanical 2012, and AutoCAD Structural Detailing 2012 or AutoCAD Civil 3D 2012 the installer will install for all of them.
Software developers are strongly encouraged by Autodesk to base all future Microsoft Windows based development for AutoCAD based products on the Microsoft .NET Framework (VB .NET, C#, managed C++ etc).
If Autodesk’s future versions (AutoCAD 2013?) still will be able to run VBA or not only future can tell but don’t hold your breath.
JTB World offers fee based porting of LISP or VBA applications to .NET.
