This is a pattern that bothers me with Microsoft software on Windows. They leave the stuff they needed to use ALSO for installer stuff in an installer directory, not under my path, not even in a place I might know of. You could have said

%APPDATA%\VisualStudio\VC2932.2.1.21113412\1231231\a31\Internal\Installer

and it would have been just as easy for me to find.
