I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
You can install the program from a fresh download over itself for the purpose of being able to uninstall it.
If that fails go to C:\Program Files to see if you can find it in either folder. If so Take Ownership of the folder to delete it:

If that doesn't work then delete the folder from Repair Mode or Boot Mode Command Prompt where WIndows has no say, using the mini-explorer in Notepad same as shown here: http://answers.microsoft.com/en-us/windows/wiki...
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
