Windows 7: Unknown program trying to install itself

Unknown program trying to install itself

I keep getting a Windows installer pop-up saying that "Another version of this product is already installed. Installation of this version cannot continue....." I click "Ok," and the pop-up goes away but comes back.

I'm not trying to install anything, and I don't know what program may be trying to install or update or whatever it's doing. Is there a way to find out what program it is so I can get it to stop?

Type EventViewer in the Start Orb, search box, and then select it from the list that appears. Under Windows Logs > Application, have a look to see if any of the entries listed might correspond to the attempted installation.

Let us know if you need more help.

Thanks. It appears to be Dell Support Center and/or PC-Doctor. When I go to the control panel, I'm not able to uninstall it because it's asking for the installation disk, which of course I don't have.

Have a look at this little guide at the link below to see if there's an entry in the Windows 7 startup folder (msconfig) that could be causing this to keep trying to install, if so see if disabling/removing the entry will sort the issue for you.

Troubleshooting with MSCONFIG

Here is the full-grown tutorial, I just feel the little guide is easier to use for what you need.
