System is XP. I noticed recently that several programs won't load. One freezes at the initial screen, two others tell me the encountered problems and need to close. I've tried deleting and re-installing, but then I come up with a Windows installer error. So, I followed the advice online from Microsoft and unistalled that, and reinstalled the new version. No luck. I also restored my computer to a previous time w/o and luck. I also emptied my cache, temp files, temp internet files, etc etc. I'm a bit hesitant to use any register repair programs(if that is, in fact, the problem), but maybe one would help.

Any experts out there have any ideas? No, I don't want to re-install XP!

Have done that. Have run four anti spam and one anti-virus.

my vista lap top was getting buggy as heck... bought a program called regzooka online from blue penguin software. It fixed 1100 registry errors and now its back to like new performance.

CCleaner can clean up the registry... ComboFix works wonders on rootkits/malware/spyware. :-)

Have run ccleaner. Not familiar with regzooka. Will look into that.

Have you updated Windows Installer to V4.5?
