Yinzer Posted March 31, 2020 Share Posted March 31, 2020 Ccleaner suddenly stopped opening. I have CCleaner Professional. I uninstalled and reinstalled the ccleaner program. It opened and worked once. After I exited and tried to open it again by double-clicking ther icon on my desktop, it would not open again. What to do?

What to do? What anti-virus are you using? What operating system are you running?

This 'only run once following install' behaviour is a sign that a programme is being blocked from running by your antivirus programme. So as Hazelnut asked which AV are you using? *** Out of Beer Error ->->-> Recovering Memory *** Worried about 'Tracking Files'? Worried about why some files come back after cleaning?

Moderators nukecad Posted April 8, 2020 Moderators Share Posted April 8, 2020 We suspected as much which is why we were asking. More than one user has reported that once Trend Micro is updated to 2020 then CCleaner works as expected again. Updating Trend Micro from within Trend Micro itself will tell you that you are up to date - but you may not be. You may have the 2018 or 2019 versions of TM, so while that version is up to date itself it is not the latest TM version. You may need to download and install the TM 2020 upgrade - go to this page to 'grab' the 2020 upgrade.https://esupport.trendmicro.com/en-us/home/pages/technical-support/maximum-security/home.aspx If that still doesn't clear the problem, try Whitelisting ccleaner in Trend Micro 2020 following the directions in this posthttps://community.ccleaner.com/topic/57702-ccleaner-not-working-after-update/?tab=comments#comment-317617 We are told that Trend are aware of this issue and that their engineers are looking for why it has suddenly started blocking CCleaner. *** Out of Beer Error ->->-> Recovering Memory *** Worried about 'Tracking Files'?
