[Ccleaner no longer installs or starts on Windows 10]

Everything worked. What I've done.

I went to Event Viewer, Windows log. There in the applications, I found the ccleaner log crash. Found a topic in google on the forum https://community.ccleaner.com/topic/47911-bug/

I debug the mod, ccleaner tormented something, while I was reading the log, it started to start normally.

The problem was in the license, that the license expired and ccleaner crashed and did not want to start.

Now the program works fine, apparently it's some old bug in the program.

sanctions by the EU on 24th June 2021

I'm from Belarus. A check by the kaspersky team showed that there were no viruses on my computer.

Here is a link to their forum thread https://forum.kasperskyclub.ru/topic/84682-ccleaner-perestala-zapuskatsja-na-windows-10-x64-pro/

Is it because of the sanctions? Sanctions only make ordinary people worse, and not against whom they are directed...

You did mention a Defender setting - but do you have any other AV/AM installed?

No.

'Exceptions' where?

Windows Defender.

Also - In the Defender Potentially unwanted app blocking does the 'Protection History' show that it's blocked anything CCleaner related?

Empty.

I will try to ask for help on the forum  forum.kasperskyclub.ru. Maybe it's because of a virus.

Make sure CCleaner is uninstalled then try installing the Slim Build (last in list) from here

The portable version did not start. The Slim version installed but did not start.

I turned off the Defender. I turned off Defender - Potentially unwanted app blocker.

It didn't fix the problem.

The program stopped starting after the last Windows update. I uninstalled it to reinstall it, but now it won't install. After clicking the Install button, the installer is closed.

I've tried adding file and folder to exceptions. Even added an installer to exceptions. Tried installing to another drive. It didn’t help.

What to do?
