CCleaner Free Crashes on Custom Clean for Non-Admin. Crashes around 90%.
Doesn't crash on Admin account.
On Windows 10 Pro, 16 GB RAM, nothing else running.
We have seen similar before.
In those cases it was/is a permissions issue and the fix was to 'Run CCleaner' from within the installer as the last step of the install.
The Standard Installer does that by default now, (unless you X out of it), but the Slim installer still gives you a tickbox choice to complete an install without running CCleaner to finish.
If you haven't already 'Run CCleaner' as part of the install then please reinstall CCleaner and 'Run CCleaner' from within the install.
There is no need to uninstall the current one first.
You can find and download the installers here if needed: https://www.ccleaner.com/ccleaner/builds
If you have already 'Run CCleaner' as part of the install and CCleaner is still crashing for a non-admin user then can you say how Custom Clean is 'crashing' for you.
Does if freeze or close the window? Does it give any error message? If you look at the top of the results panel then what does it say it is cleaning when it crashes?
ie. what does it say here:
