WinXP: Missing Registry Key HKLM\SOFTWARE\Microsoft\VisualStudio\SxS\VS7
For whatever reasons the following script in vcvars32.bat
was attempting to
detect the key in order to be able to run the compiler, but the key was never
installed. This is a blank slate installation of WinXP with compiler tools
so there isn’t a reason for the key not to be deleted off as one of the
StackOverflow
answers suggested.
The way to resolve the issue is to enter the key manually using regedit.exe
