[cvsnt] Problem with post install custom action

[Casey Schmit]

I was having a problem getting a CVSNT(1927) install to complete
successfully.  Everything would install and appear to be running properly,
but the install would drop at when attempting to clean up backup files.

After generating an msi log and using filemon to figure out what was up, it
appears that the final custom action that is launched from the installer
requires that the new VC files(msvcr71.dll, msvcp71.dll, and possible
mfc71.dll) to be located in the system path.  However, these files are not
present, the action fails to load, and the install reports a failure.

The installer should either lay these files down into the system32
directory(since they are packaged as part of the install anyways) or the
custom action should be statically linked to the C runtime.  Once these
files were added to the system32 directory, the install completed without a
problem.

Thanks,

Casey
