Everytime I try to open Adobe Reader or a PDF, I get an error message saying that Adobe Reader can't open in Protected Mode due to an incompatibility with my system. It offers me the option to open with Protected Mode disabled, but when I choose that option I get a message that says failed to load Core DDL. I tried finding answers online, and some people said that uninstalling Adobe Reader and reinstalling and then rebooting their computer fixed the problem. I tried this but it did not work. Please help!
I've seen the same thing in the forums the last few days. I haven't run into it myself, but have you used the cleaner tool to uninstall, that may do a more thorough job?
I would run that, then reboot and do a fresh install, see what you get. Worth a shot.
