I have a program that uses Reader 3.0. I cannot get around that version to get this program to work, but once I install it my current version of reader does not automatically work. For instance, I try to open PDFs from websites and they just give me errors (because 3.0 can't open 8 files) How do I have both versions and stop the errors??? Ideas?
As 'graffiti' states, you cannot have more than one working version on one (Windows) system. If I were in your situation I'd install Virtual PC, and in there a second copy of Windows. Run one copy of Adobe Reader in there, and the other copy on your main Windows.
