It's likely that Perl hasn't been installed on DFM server (Perl is necessary for MCTB on Windows DFM servers). Please use Active State perl, as we have had problems with other distributions. Here's a link: http://www.activestate.com/activeperl/downloads
Don't buy anything! Perl is free, but ActiveState does provide commercial products wrapped around their Perl distro, and sometimes it looks like you need to buy something to get it, but you don't.
Let me know if you have any more questions or issues.
Yeah, I never install Perl under Program Files, or any other path with spaces in it. It causes too many problems. It's a drag that the default installation directory for the ActiveState installer is under Program Files.
Does that resolve your issue, or are you still having problems?
