If you are using version 5.45, try going to an earlier version and see if the issue still occurs.

previous versions available at FileHippo.

Are you running Kapersky internet security or antivirus?

I have the same problem, CCleaner crashing a few seconds after the start. I use Kaspersky internet security 2019 and CCleaner 5.44. Without KIS CCleaner works fine. It started tonight. Help me please:(

Kapersky is looking into the why, but here's the work around

This did not help, unfortunately. I have a different situation: CCleaner crashing after the start of the program itself, rather than after clicking a button "Run Cleaner" in Ccleaner.

Ah, that also maybe what Kaspersky is currently looking into. Maybe light a fire under their butts. The ccleaner dev may also be looking into this but i'm unsure of that.

I found the problem! The problem is the parameter "Enable Active Monitoring". If it is turned on (as if by default), the program works fine, but if you disable it, the Ccleaner crashes right after the start. Please tell the developers about it. I hope this is fixed in the next version.

By the way, on version 5.43.6522 there is no such problem with KIS 19, I just installed and tried it. Although this problem I did not have and on version 5.44.6575 and KIS 18, but yesterday I installed the version of KIS 19 and it worked fine with Ccleaner 5.44 wiper within 24 hours and the problem appeared tonight.
