I had a weird problem today when I installed the newest build on a Vista machine for someone else.Usually, there isn't too much I cannot figure out with computer hiccups but this one bugs me.
Here's what I did. I uninstalled the 5.0.677, rebooted and then cleaned up the leftovers. After a few more reboots i installed the latest version and as soon as the new registration box popped up the error message that "Windows Internet Explorer will not Run". So, i rebooted and then when the computer started the same error message came when Windows was supposed to boot. Except this time it said "Windows Explorer will not run". Once in Safe mode, it ran but once booted normally the issue remained.
After a few restore's and uninstalling and reinstalling, the only time this happens is with the new version installed.So I've reinstalled build 5.0.677 and all is well on the machine.
For now, I told the lady to ignore any reminders from the Avast! program to update the program and only accept the definitions updates.
It's a Gateway laptop computer.
Any ideas?
