I never used the Pro Trial version before, but found out that also the Slim version had been updated (new Hash).

After installation of ccsetup5.66.7716_slim.exe (free), so far everything looks OK. Will keep you posted in case new problems will arise.

What I don't understand is, what has the Pro Trial version to do with the Slim version?!

Sorry, have not tried it out as I deinstalled latest version and went back to ccsetup5.65.7632_slim.

I Just can confirm, as JMallorca, that I also had error reports in Win10 Reliability Monitor

I can confirm bug described by nontrade and JMallorca

When opening Ccleaner it closes by itself within 2 seconds. No action to run or select a task possible.

Previous version ccsetup5.65.7632_slim works without any problems.

No changes in Win10 user account made between installation of Cleaner 5.65 and 5.66.

Effected version: ccsetup5.66.7705_slim.exe (free)

System: Win10 1903 built 18362.778 (latest updates)

Anti-Virus did neither identify Ccleaner 5.66 as virus nor did it block it.
