One of my clients was running version 9, so I upgraded him. Now I get "ESET Main GUI has stopped working". I got the message immediately after installing. I get the message when I start the computer. It's happening right now with version 11.0.159.9 (the most up to date version). I uninstalled using the ESETUninstaller.exe in safe mode. I installed version 10. Same thing. I tried using a retail copy from a CD. That just downloaded the most up to date version that previously failed. The computer is running Windows 7 Home Premium, 64 bit, SP1. I've searched quite a bit for a fix. But everything I've read says to uninstall and reinstall the most current version, and that doesn't work. Any other ideas?
