Moderators Nergal Posted April 3, 2020 Moderators Share Posted April 3, 2020 What antivirus do you use? What windows version? ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.

Win 10 Trendnet AV...was working fine prior to last week Do you mean trend micro AV? I couldn't find trendnet on a cursory web search. If yes Trend micro users have found that one of two things fixes this issue First make sure you are running trend micro 2020 (update within the program won't do this update). It's available at https://esupport.trendmicro.com/en-us/home/pages/technical-support/maximum-security/home.aspx Second if that doesn't fix the issue or you are already on 2020 Add ccleaner as a whitelisted program as described in https://community.ccleaner.com/topic/57702-ccleaner-not-working-after-update/?do=findComment&comment=317617 ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF.

karniplayer Posted April 6, 2020 Share Posted April 6, 2020 (edited) I have the same problem. After the update to v5.65, ccleaner could not be opened anymore. I also tried the Portable version. Since I had to reinstall my PC anyway because of problems, I didn't care. After the reinstallation, however, the same problem again. After reading here that it might have something to do with the virus scanner, I tried it right away. If Trend Micro is completely closed, ccleaner v 5.65 can be opened, otherwise not (also Portable!). ccleaner v5.64 works without any problems! Win10 pro 10.0.18363 Trend Micro Maximum Security v16.0 ... Update OK, who can read is clearly in advantage... After I have included ccleaner in the whitelist of the TMMS it works again. Funnily enough, I've never raised problems with ccleaner and TrendMicro and I've been using both forever...

MM&I Posted April 7, 2020 Share Posted April 7, 2020 Re: Quote Funnily enough, I've never raised problems with ccleaner and TrendMicro and I've been using both forever Me too; I have been using both TrendMicro Maximum Security and CCleaner for years, but after the update sometime in March 2020, (in V 16.0 anyway), that is ... ...Something changed somewhere. I don't know where the change occurred, but the white-listing in Trend, did solve the problem. Link to comment Share on other sites More sharing options...
