CCleaner 5.42.6495 (64-bit) crashing

CCleaner for Windows CCleaner Windows Bug Reporting
1

CCleaner 5.42.6495 (64-bit) crashes every time I try to use it. Could use some guidance. Attached debug log Also attached file Report.wer from C:\ProgramData\Microsoft\Windows\WER\ReportArchive\AppCrash_CCleaner64.exe_<long hexidecimal string>\ (not generated at same time as attached debug log).

Crashes happen when I press "Run Cleaner" in the Cleaner, independently of what is checked off. It'll crash when only "Empty Recycle Bin" is checked, and when only "Game Explorer" is checked, but no crashing when nothing is checked. Does not crash when "Analyze" button is pressed.

Tried uninstalling CCleaner, deleting all associated files and registry entries, and reinstalling. Not helpful.

System is Windows 10. No problems or errors detected when running these checks: 

  "chkdsk c:"


  "sfc /scannow"


  "Dism /Online /Cleanup-Image /CheckHealth"


  "Dism /Online /Cleanup-Image /ScanHealth"

What antivirus do you use?

Kaspersky Total Security, and nothing else. Disabled it and tried Ccleaner again, still crashes.

Crashed in safe mode.

Uninstall ccleaner

Update kaspersky to the latest patch

Reinstall ccleaner

Should no longer crash

Did as you instructed, still crashes. :-(

But it was a good idea, I have to disable Kaspersky when I install a new version of the VirtualBox Extension Pack.

Tried again 9:41pm PST, same result.

I have same problem on CCleaner 5.42.6495 on W10 64. Just started yesterday. CCCleaner launches, but when I run "run cleaner", get the windows message "CCleaner has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available"

I also have Kaspersky Internet Security. Tried uninstalling and reinstalling CCleaner. Ran avast uninstall just in case avast got installed with CCleaner causing a conflict with Kaspsersky. Restarted. Made sure Kaspersky definitions database was all up to date. Then reinstalled CCleaner again. No luck. Weird. Have been using CCleaner over a decade and this is the first time I've had a problem.

The developers have acknowledged the bug with Kaspersky and ccleaner. For many the instructions I put above work, obviously from this thread it can be seen that it doesn't always work

Thank you for the update. I've reverted back to 5.40 (downloaded from https://download.ccleaner.com/ccsetup540.exe). 5.41 also works, but I don't like the functionality changes to CCleaner introduced in 5.41. Let me know when this is fixed.

Wow. 

5.40 is 11,217,568 bytes.


5.41 is 15,333,512 bytes.


5.42 is 15,813,864 bytes.

Those are quite big changes.

Yes, moderators also noticed the size change and have commented on it to developers

Thanks everyone. I reverted to 6.41.6446 (64) All is well now. Hopefully Kaspersky conflict will be resolved in a future release.

Try setting the option as shown in the attached pic. I started having this problem when I installed Kaspersky Internet Security 2019 V19.0.0.1088(a)RC and this stopped the crashing of CCleaner 5.42.6499 when "Run Cleaner" is executed.

SiliconMan01, thank you! Your solution worked for me. However, I have the purchased version, so my option was in the same place, but under "Cleaning results level of detail," third radio button choice. Thank you again!!! :)

This issue disappeared when I installed 5.43.

Thanks for the fix. My favourite cleaner now works as it should.. What does save to ini file do as I now have that checked.
