That is not suspect; internally, TL mostly uses forward slashes,
although it tries to use backslashes when talking to windows.
Surprisingly often, windows does not even care.

What IS suspect is the inability to spawn cmd.exe. Are your path
settings correct?

Also, I saw mention of cygwin in your output. Are you sure that
cygwin is not interfering?

I did some testing myself with a UNC installation and a UNC temp,
but that does not seem to be the problem.
