Hello,
I've been trying to install CCleaner recently. I used to have it on this computer a while back, but whenever I tried to run a scan, it would crash. I tried uninstalling/reinstalling CCleaner, and it didn't work, so I gave up on it. Here I am now, and I am making the post I never bothered to a while back. Whenever I try to install CCleaner, be it the trial, free download, or slim version, the installer crashes as soon as I hit the 'Install' button. I've checked task manager for any preexisting CCleaner instances, but there is nothing. When I attempt the installation with task manager open, I see CCleaner run only momentarily before completely disappearing. It doesn't matter if I run the installer as admin. I've tried clearing any CCleaner-related files, renaming the installer, running the portable version, launching the installer in compatibility mode, disabling antivirus, and trying to install in safe mode.
When I try installing older versions of CCleaner, I get a popup saying that it is incompatible with my current version of windows (this is even, like CCleaner 5.4 or so)
I get no error messages at all, CCleaner just disappears.
However, when running the installer in safe mode, I get a windows error message:
Error completing operation 0xc0000005 at address ...
A cursory google took me to a microsoft support site, recommending I chkdsk and run the Windows Memory Diagnostic. I did that, but that only fixed a different issue (My PC would only boot successfully on every other attempt; I'd get to the windows logo with no loading animation, then have to hard-reboot in order to use the machine.)
After the chkdsk and memory diagnostic, I still got the same error message-- Error completing operation 0xc0000005 etc. (quoting error message from memory, I can boot into safe mode and verify it if that helps)
I've tried a lot of things, probably all "common solutions", none of which have helped me install CCleaner.
Below are system specs:
Windows 10 Home Version 1903, build 18362.657
AMD FX(tm)-6120 Six-Core Processor 3.50GHz
