Exactly :)

Ah yes, reg [location] /s to search... This does run into a similar  
problem with versioning.  There seems to be no standard key for the  
toolset (HKCU\Software\Microsoft\V???)--there is Visual Studio, which  
has a vsvars32.bat (that should be standard) and there may be one or  
more different Visual Studio packages, with the actual tools and  
settings for the installation, such as VCExpress for Visual C++  
Express.  The best key available would be the same as the  
VSnnCOMNTOOLS env variable: HKCU\Software\Microsoft\VCExpress\Setup\VC .
