I had the same problem, I tried to uninstall with CCleaner, and directly with Windows, but it looked like CCleaner browser was running and didn't let windows uninstall. It just asked me if I wanted to uninstall and then nothing happens, and I could not finish nor end with task manager the process running CCleaner browser. What I did? For me this worked.
First just using CCleaner in the Start up part, I disabled CCleaner browser from initiating on turning on computer.
Then just restarted (made sure CCleaner wasn't running) and tried again to uninstall with Windows and it worked. Hope
