Visual Studio 2005 and older
In the rare situation where you want to remove Visual Assist from Visual Studio but retain it for Visual C++ 6.0, open a command prompt and cd to the Visual Assist installation directory. Run:
regsvr32 /u vassistnet.dll
regsvr32 /u vapkg.dll
cd to the directory with devenv.exe for Visual Studio 2005 or Visual Studio 2003, and run:
devenv.exe /setup
Note: Removal of Visual Assist from Visual Studio 2005 also removes the software from Visual Studio 2003. You are left only with Visual Assist for Visual C++ 6.0.
