Just ran CCleaner and now it seems I am missing a windows file. So, I had made a backup file before running CCleaner. But when I go to that backup file and select merge from the menu, it asks for an association to be made before it will restore. First time this has happened. So, when I look under file types it has nothing associated with the file in the "open with" part. If I go into advanced and try to choose a program to open with, and select CCleaner, it says adobe will open that reg file type. So, I am not used to using the file association program so can anyone let me know what I am doing wrong to fix things?
