I'm a long time user of the free version of CCleaner with no issues in using it or upgrading it as new versions come out. When I tried to update to the most recent two versions (5.34 and 5.35), I got an error message "Error opening file for writing" "C:\Program files\CCleaner\CCleaner64.exe". I tried removing the program and re downloading it and I've since updated to the Professional version and downloaded it, but I continue to get the same error message. Thanks for any help.
