CCleaner is great, but for some reason it messes with just one program called "Rcon4CoD" (always have to re-install it after running CCleaner) Is there a way to get CCleaner to stop picking on it. Maybe exlude the folder or registry or both?
You need to find out what's causing the problem as it could be either file related if the program stores something in a temp folder. Note that allot of programs rely upon Adobe Flash Player so make sure it isn't that, if it is untick the cleaning of Adobe Flash Player.
If it's registry related you could exclude the key.
