Installation directory

Visual Studio 2010 and newer

Visual Assist is installed to a per-user, IDE-specific directory that varies with system configuration and method used to install Visual Assist (.exe or .vsix). By design of Microsoft, the installation directory is not user-selected.

If the following Extensions directory contains multiple random-hash directories, use the presence of VA_X.dll to identify the directory containing Visual Assist.

Visual Studio 2017 and newer

%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\<IDE version>_<random hash>\Extensions\<random hash>\

Visual Studio 2012-2015

%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\<IDE version>\Extensions\<random hash>\

Visual Studio 2010

%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\Whole Tomato Software\Visual Assist X\<version number>\


%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\<random hash>\

If you have recently installed Visual Assist, have not since started Visual Studio and already had Visual Assist installed, you may find VA_X.dll in two directories -- one directory with the previously installed version and a newer directory with the updated version. Visual Studio removes the older version when it starts.

Visual Studio 2008 and older

Visual Assist is installed for all users to a user-defined directory that defaults to:

%ProgramFiles%\Visual Assist


%ProgramFiles(x86)%\Visual Assist
