|If you DO NOT have Office 2007 or higher installed on the system, search the web for: "Windows Installer Cleanup Utility" .|
It's a Microsoft program but they're no longer offering it on their web site because it causes problems if you use it to remove something if your system has Office 2007 or higher on it (or any program that is an Office 2007 or higher component - e.g. Outlook [not Outlook Express which is built into Windows], Excel, Powerpoint, etc. ).
Download it, double click on the download to install it, run it, and delete the listing for American Greetings whatever.
Re-start the computer, then install the software again.
It will work with any program that was installed by a Windows Installer software package.
