linney--that's a good point--I'll have to check that out. The errors they receive are the kind like "The font is currently in use" when it's not even installed on their system. They're the kind of errors I've seen when Windows doesn't want to say "Hey--you don't have permission to do this!"
My main goal for this is to remove Power User privileges for a specific group of graphics people, but I don't want to have visit twenty machines every time they buy a new font. undercovr, I've never had much success with merely dragging or dropping font files into the font folders. I can do that remotely with a script with haphazard results.
