Have you updated Trend Micro to the 2020 version?

Many users have reported that once Trend Micro is updated to 2020 then CCleaner works as expected again.

NOTE - 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 need to download and install the TM 2020 upgrade https://www.trendmicro.com/en_gb/forHome/products/downloads.html

If that still doesn't clear the problem, try Whitelisting ccleaner in Trend Micro 2020 following the directions in this post

Thanks...updating Trend Micro and Whitelisting ccleaner in Trend Micro worked

[cCleaner not Launching]

CC Cleaner does't launch (Windows 10 w/Firefox browser).   Recent issue has worked fine over the past year or so.  Disabled Trend Micro Anti-Virus but still doesn't launch.  Have uninstalled and re-installed cc cleaner but still does not launch.
