My Install also crashes or doesn't even start to install since v5.64
Never had a problem before even with these running & not disabled. Really miss my ccleaner!
I have been having this same problem. I note that the version of ntdll.dll shown in the problem signature is dated 1/2/2020 (I suspect that it was installed be the final WIN 7 update KB4534310). Could there be some incompatibility between the newer CCleaner versions and this version of ntdll.dll?
I found out that 0Patch is causing the problem - see https://0patch.zendesk.com/hc/en-us/articles/360013175099-CCleaner. I've applied the fix, but it still won't work so I've reached out to them again. Will post followup when I hear fromthem.
OK, I am running 0patch, but i thought I had eliminated that as the problem by excluding CCleaner through the 0patch dashboard and then also by disabling the 0patch agent. CCleaner continued to crash in either case. I guess the problem is more subtle than it would seem. I am leary of mucking about in the registry, and since that didn't work for you I am going to wait for your followup. Thanks for the heads up.
Latest is that they left out a registry modification step in the fix, but after doing that I still haven't gotten it to work. You might should notify them of your problem too - support@0patch.com.
Finally got it working on the PC after 0Patch updated the instructions (see link above) a couple more times! Still not working on laptop though; might need a reboot.
Working on laptop now. Had to uninstall 0Patch and CC, then reinstall CC and 0Patch, then do the fixes.
