this is more of a guess than solution. Right click on icon and select 'Run as administrator'

I'm having the same problem, not quite sure whether it is happending due to upgrade to IE 8 or Windows Installer 4.5 installation. Cleanup and re-install of Yahoo Messenger 10 won't help. The YahooMessenger.exe fails to initialize right during the installation process.

Could be a virus called WORM_KLEZ.E
Do a virus scan.
If theres no visrus try using system restore back to when the error message wasnt there.
Make sure automatic updates are turned on.

Try system restore.

You can reinstall the entire operative system with the CD that comes with your laptop, or with the restoration partition. See user's manual. This is the best way to fix error in a PC. Before restore the OS, backup your personal data.

re install windows - your computer has crashed.
