Hey mate,
Crazy late to the response, but I just had a similar issue and found your thread.
If you're still having the issue, I found the location for this software is actually in Program Files, NOT (x86). Locate the Uninstall file there, it should completely remove the software.
I had a pesky "start" file in there that stayed and prompted me to run the .exe each time my PC started, had to manually delete the Tt folder from Program Files after uninstalling.
Hope this helps.
