when trying to open a document an error message pops up saying,"the acrobat/reader that is running cannot be used to view pdf in web browser.Acrobat/Reader 8 or 9 is required."
If I click ok on the message it tries to open Acrobat 6. I have both installed but i cannot open docs through 9
This may or may not be the reason but I suspect it's because you have both Acrobat and Reader installed. It's not recommended or supported to have both on a Windows system.
Try uninstalling both the reinstalling Acrobat to see if it clears up. If it does then, that's the problem.
