Just to add an extra bit of info. Adobe are now giving away CS2 for free. That has Acrobat 8 pro in it, and when I installed it on someone's machine at work it said "Install Autocad Drivers"
Careful with that. The official Adobe stance is that is *only* to support activation for users who have previously purchased a license. While they are unlikely to legally go after "oh goody, FREE!" downloaders at this point it would probably be best to respect the intentions if not the technical implementation.
If you are going to fly by the seat of your pants, expect friction burns.
Adopt. Adapt. Overcome. Or be overcome.
