Resolution

The CA Gen 8.5 Build Tool (BT) script callvsvars.scr uses the appropriate installed Visual Studio (VS) environment variable (based on BT token value OPT.VSVERSION), to setup the VS environment by calling file "%VSXXXCOMNTOOLS%vsvars32.bat", where XXX represents the VS version (XXX=100 for VS2010 or XXX=110 for VS2012).

After checking the value of environment variable VS110COMNTOOLS it was found to be set to a series of ";" separated directories instead of the expected single directory value:
<VS_INSTALL_DIRECTORY>\Common7\Tools\
e.g. for default install directory:
VS110COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\

Correcting the value of VS110COMNTOOLS to point to above single directory resolved the error.

Additional Information

When using a custom install directory for the Visual Studio 2012 install, problems with the setting of VS110COMNTOOLS and other problems after running "%VS110COMNTOOLS%vsvars32.bat" have been reported. See CA Gen EDGE Community post: Build Tool Error
