Windows XP Installer Pops up when booting

[scrooge]

When I boot up my Windows XP computer, a Windows Installer pop-up appears saying "The feature you are trying to use is on a CD-Rom or other removable disk that is not available. Insert the "Sonic-Update disk and click OK." I also get others for iTunes.
This also happens whenever I try to install a downloaded program, so I can't install anything.
Help would be appreciated!

I'm using Zone alarm firewall, Avast anti virus, AdAware anti-spyware, and Trend Mirco Anti-spyware.
No, the computer doesn't crash.

Get and try the Microsoft Fix installed.

Windows Install Cleanup it's called.

It's not a Window Update item.
