I downloaded and installed the newest version (running Windows 10). When I started CCleaner at the end of the day, it would start to open to the main desktop and then almost close after no more than 2 seconds. This was when I was running in user (non-administrator) privileges. I tried it several times to prove that it wasn't an operator error.
When I right clicked and ran the program in administrator mode, the program seemed to work as usual. I used this to delete all the files.
But then I tried user mode again, it stayed up and I clicked "analyze". It should have shown very few files to be deleted. I had a Chrome browser open (writing this note) . But when I ran an analysis, it showed that there were files to be deleted - about what it showed before I ran the program in administrator mode. So I am not sure it did any cleaning at all.
Then without making any changes, I tried again to open up CCleaner and got the same shutdown. And when running again in Administrator mode, it did not show any of the files.
I suffer the same problems. In Reliability Monitor I find the following report:

@nontrad
I think that you have two seperate issues here.
Firstly
If Chrome was open then CCleaner would Skip the cleaning of it, which may be causing part of what you are seeing. (Especially if you have the 'Skip' warning turned off).
CCleaner cannot clean anything that is open/running.
Second
It seems that you are normally using a user (non-admin) account, if so then which account is CCleaner installed on, user or Admin? and is it the Free or Pro version of CCleaner
The Free version can only clean the account it is installed on.
Pro can clean all user accounts from an Admin account, if it has been set to do so.
I don't think that Pro can clean all accounts from a non-admin account though, unless possibly if run as Administrator from a right click?
Again that seems to fit in with what you are reporting.
I am aware that it will not clean Chrome files if Chrome is open. I wanted to point out that this was the only time the program did not crash in user mode - although i could not replicate that.
I normally work on the computer with my account that has user privileges only - and CCleaner is crashiing when run normally. If I right clicked to run it with administrator privileges on that account (not in my admin account), it did not crash.
My comment is that CCleaner is NOT WORKING when it is an account with non-admin status and not running in Adminstrator mode.
(BTW, I have a BSCS and cyber background and sorry fr the typo in the title at midnight)
Sorry, you previously said that it was working if you run as administrator?

As for files being found again after you have just run CCleaner,

that is normal and is just the way that Windows works.

I'm more interested in the opening/closing immediately behaviour you report if it is run as a non-admin.
Again are you using the Free or the Pro version of CCleaner?
And, (of particular interest at the moment), what anti-virus are you using?
I can confirm bug described by nontrade and JMallorca
When opening Ccleaner it closes by itself within 2 seconds. No action to run or select a task possible.
Previous version ccsetup5.65.7632_slim works without any problems.
No changes in Win10 user account made between installation of Cleaner 5.65 and 5.66.
Effected version: ccsetup5.66.7705_slim.exe (free)
System: Win10 1903 built 18362.778 (latest updates)
Anti-Virus: NortonLifeLock
Anti-Virus did neither identify Ccleaner 5.66 as virus nor did it block it.
Thanks for that confirmation @ROC_172
What happens if you right click it and 'Run as Administrator'?
I'll flag it up for the staff/developers to take a look at.
Sorry, have not tried it out as I deinstalled latest version and went back to ccsetup5.65.7632_slim.
I Just can confirm, as JMallorca, that I also had error reports in Win10 Reliability Monitor
@nontrad; @JMallorca; @ROC_172
There has just been a minor update issued to take CCleaner to v5.66.7716
Apparently there was a bug in the Pro Trial that was causing this open/dissapper issue for some users, and users report that this update has fixed it.
Please let us know if the update works for you.
I never used the Pro Trial version before, but found out that also the Slim version had been updated (new Hash).
After installation of ccsetup5.66.7716_slim.exe (free), so far everything looks OK. Will keep you posted in case new problems will arise.
What I don't understand is, what has the Pro Trial version to do with the Slim version?!
The trial option is built into CCleaner whether you choose to use it or not.
The 'Standard' and 'Slim' installers are just different installers, they both install exactly the same CCleaner.
Why are there 2 different installers? (3 if you count Portable, which isn't an installer just the bare programme).
The Slim/Portable were originally intended for technicians and advanced users, who may be doing a lot of installations or wanted a CCleaner they could carry round on a USB stick.
Nowadays the graphics used by the user offers in the Standard installer will not work with Win7 or older, and so the Slim is the option if you want to install CCleaner on Win 7.
It also gives another option if someone is having problems installing.
@nukecad
Thanks for the comprehensive answer!
The update of the application has solved the problem. It works as beautifully as it did before. Thanks.
Well I'm not a developer so the thanks are due to them for fixing it quickly, but it's good to know that the fix worked.
