When a user attempted to install the newest update to symantec endpoint protection (ver 11.0.2), he began recieving interactive services dialogs that said the product was uncompatible with vista. I attempted to uninstall version 11 (it hadnt been replaced) and reinstall the newest version (11.0.2) and recieved a runtime error during the install. The runtime error said that the program (C:\Program Files\SymantecAntivirus\SMC.exe) had requested the runtime to terminate in an unusual way. When I closed the error, the install finished. When you tried to open symantec, another error popped up that said "CMC SMC stopped working and was closed. A problem caused the application to stop working correctly. Windows will notify if a solution is avaliable." When I rebooted the machine, the DKservice.exe stopped working and was closed and symantec antivirus/antispyware protection was disabled. The auto-protects for email and file system were not functioning correctly AND on top of this, I am still getting the interactive services dialog every couple minutes.
I will be placing a call to symantec too, but I was wondering if anyone on here had any ideas.
