I stumbled upon REVO UNINSTALLER. It seems to do a better job at uninstalling - it goes deeper to locate leftovers, remaiinders, etc.... I like using it. I used the Revo Uninstaller to remove the Registry Booster, and a few other 'registry cleaners' I was trying out. No Problems thus far. "They" do offer a Free Scan, but then Registration is Required to Fix anything other than a very basic cleanup (for free).
Hope this may help with uninstalling trouble.
