Glad you sorted the issue. FYI, the "off" feature has been added to berrybrew, and have done some minimal successful testing on a few Windows boxes.

If you have a previous install of Perl, we'll override it with "switch", but then the original version takes back over when you run "berrybrew off". Note that you have to open a new cmd window after you run "off" before it takes effect (thanks to Windows inability to set PATH in the current shell).
