Vlk,

I Was using WinXP sp2 for several weeks before I downloaded avast two days ago. I did change the ‘Compatibility’ mode on the original avast setup, ran setup again, rebooted and the error message on the upgrade was gone. Than I received the RPC error.

The RPC error was corrected after I uninstalled/booted/reinstalled/booted the avast 4 program. (I also ran avclear 4 when I uninstalled, and avast External Control Center to clear any Norton Antivirus files left after an uninstall, which I think helped) The program is now running great.

I wanted to explain how I applied everybody’s help and used it which corrected my problems.

When I get stuck & need help again, I’ll simply dial …avast.com.

See Ya
