Invalid Command Line Arguments

Recently I had a user, when she would try to save anything in her WordPerfect Suite 8 it started “freezing” on her. I uninstalled and tried reinstalling the application. After I finally get to the point that the install wants to do a restart, and I do the restart, the PC is finally to the point where the install is suppose to finish configuring, I get a message “Invalid Command Line Arguments. Setup will not continue”, instead of WordPerfect finishing its’ install. Any ideas?
