Windows Installer trying to Install Absent Program

Hello, This is the problem I have I installed Corel Word Perfect Office, then decided I didnt need it anymore, so I uninstalled it. However there was an error when uninstalling Now everytime I reboot, Windows installer tries to install Corel Word Perfect, then generated the error 1707 no valid source Windows installer cannot continue . I've looked in All the hidden sections any trace of word perfect could be hiding, and even deleted the registry entries, and files from C;\Users\App\Roaming\ Local Data etc.. and as far as I know, there isnt a single trace of this program left on my drive, but Windows installer persists on trying to install it when I reboot or start my PC How the heck can I stop this

 

Try windows installer cleanup. http://support.microsoft.com/kb/290301

 

Never had much luck with either windows installers or cleanup.

Try this one which should highlight system entries still in place but relating to uninstalled software

Runscanner

Is Corel still running as a service?

 

Thanks guys, the Installer cleanup removed what I could not Its gone now
