Error in Uninstalling Revo Uninstaller Pro

Hi everyone! I keep on receiving this message whenever I try to remove Revo Uninstaller Pro. When I first tried to launch the program, it said that there was a spyware, so I opened it on quarantine.

Now I want to remove this program, but I always get the error shown above.
Error
Unable to create a temporary file. Set up aborted.
Error 5: Access is denied.
I don’t know why it needs to make a temporary file when I’m trying to remove the program.
Any suggestions or ideas? Feel free to post a comment below.
Thanks a lot.
