Do you have AVG installed on another drive?
This happened to me last time and has once again happened - AVG coild not
reproduce the problem I thought it would be fine this time - it does load
when you click but the olny way to stop the boot error was to disable UAC - I
don't want to do this. Last time when I tested without UAC enabled everything
worked without error - use UAC and AVG produces this error
I was fine on first install but from cold boot error now have to uninstall
unless I want to see the error each time which I don't. I really thought it
was just the old beta but know now we have it again.
