|If it was installed by a Windows Installer software package, the Windows Installer CleanUp Utility can probably prevent it from running even when it's own un-install program doesn't work properly.|
Windows Installer CleanUp Utility
Click on the dark blue Download button on the left
It is an excellent program that was made by Microsoft but it is no longer being offered for download on their web site because they found it causes problems if a system has Office 2007 or later or any of it's components - Outlook, Word, Excel, PowerPoint,etc.- installed on it.
I have used it many times without a problem.

There is a Note in the Readme.txt file that's made in the Windows Installer Cleanup folder that says it's NOT to be used for Office 2007.
Download it, install it, run it.
If the program's software was installed as a Windows Installer software package, which is the usual situation, then the Windows Installer CleanUp Utility will list it. Simply delete the listing, close the Windows Installer CleanUp Utility properly, restart the computer, and the program will no longer run.
