Thanks for the suggestions I received but, nothing worked. Here is where Im at. I deleted all instances of CCleaner. I redownloaded CCleaner. I installed it. I clicked the run CCleaner. Nothing happened. I went to my desktop and clicked on CCleaner icon. The same pop-up came up. It says "cannot find CCleaner 64.exe". ok. I went to program filesand looked at the CCleaner setup files. There it was, 64.exe. I clicked it on and it says, you guessed it, cannot find 64exe. ok, i clicked the other files and everyone I clicked said it could not find it. Hey gang, now what?
