My PC Tuneup 2011 had been working perfectly for several months. I went away for a week and when I came home and turned on my computer, I started getting popup messages with the Access Violation listed above. I have already tried to fix it by running PC Tuneup and by uninstalling the software. The access violation prevents the Tuneup program from running, and I can't uninstall because it says there is an instance of the program running. The recommended fix for this (tray icon exit) does not work. I get another error message. I'm flummoxed. What do you suggest?
