I have re-booted. I have also removed CCleaner with the add/remove and then looked in C: for any remnants. Also did a 'search' for any CCleaner and could not find anything. Then went to website and downloaded CCleaner to desktop and then ran setup. Setup went fine but when I ran CCleaner I got the same problem. It seems like the program starts running, gets part way through, and then I get the CCleaner closed due to a problem message and if I re-try, I get the error message I mentioned in earlier post. It does seem that if i re-open CCleaner and re-run it 2-3 times, eventually it does go all the way through. Not sure what I am doing wrong. Any help would be appreciated, this never seemed to happen before. Thanks.
