On my Mac (Leopard 10.5.3) whenever I try to install updates to Reader 8.1.2 I get a Message stating: "patch failed because the application has been modified since it was originally installed. Please go to Adobe support website for more information regarding how to re-enable disabled components..."
Well, can't find anything on the support website about that. Don't think I've "modified" the program anyway. Regardless... any help out there. I've already attempted an uninstall/reinstall.
