I've been using CCleaner for many years. I ran CCleaner and it found several application path errors, after running the clean they were gone. A second scan found no more. Out of curiosity I tried another registry cleaner in analyze mode only and it found many more entries that point to file/folders that do not exist on my hard drive. I did verify that they these files/folders do not exist. Why does CCleaner not find all of these entries and clean them?
