Hi nukecad, thank you for your help. It effectively has to do with Internet Explorer. I removed all checkmarks in CCleaner under Internet Explorer, ... and the EventLog error message didn't show up anymore. Then I set the checkmarks back one by one. It is the "History" checkmark which triggers the EventLog error message ! As I don't use Internet Explorer, I left "History" unchecked ! Thanks a lot ! Roger

Thank you nukecad and sorry for posting in the wrong forum ! But it is exactly the same message I am getting on every run of CCleaner (version 5.76.8269) and without having added WebcacheV01 to the inclusion list ! Winver is: Win 10, 20H2 19042.746 I add the EventLog after the last run of CCleaner at 9.55 CET this morning. Kind regards and thanks for any possible solution

I get the same error (in EventsLog) whenever I use CCleaner (without having added the webcachev01.dat file to be cleaned). Tried every hint you can find in the Internet (adding "administrators" authorizations in the registry to {0358B920-0AC7-461F-98F4-58E32CD89148}, as well as to {3EB3C877-1F16-487C-9050-104DBCD66683}, authorizations in DCOMcnfg for RuntimeBroker, tec. Must be a bug.
