Uninstall problem. No permission to Delete Files

I've followed the Install/UnInstall PDF and have both uninstalled the program and deleted the service account in command prompt. When it comes to deleting the Directory there are several folders that I do not have the permission to delete.

I have Vista with Administrator privileges and UAC disabled. I've tried fiddling around with each file settings in order to try to find some way to delete these files, but with no success.
Thanks in advance.
