After I press the 'Scan for Issues' button..
Problem: Unused file extension Data: ?- Registry key: HKCR\?
shows up. I tried clicking 'Fix issue' and 'Fix all issues' but it isn't deleting the registry key. This has happened to me in the previous version as well..but the funny thing is that it doesn't start happening until a couple days of me using CCleaner. I got rid of the last version of CCleaner b/c of this annoying bug..and figured it'd be fixed in the updated version but I guess not. Any ideas? ..it says that this registry key is left behind from uninstalling software but I don't recall uninstalling any software recently. Please help! ..thanks in advance!
