[CCleaner won't open since recent Windows Update]

Not really. Just do which ever way you find easiest for you.

 

I disabled the ethernet, wi-fi, etc. and at least when I tried to open the ccsetup569.exe file - it installed up to 93% and then closed.  BUT it still didn't install.

When you have the CCleaner installer on your machine try disconnecting from the internet.

Now try and install CCleaner.

Then connect to the internet again.

This has worked for some with install issues.

 

 

Hazelnut - do you have a preferred way to disconnect from internet (i.e. unplug connection/turn off wi-fi router/etc.)??

Bump - I just tried to install version 5.69 (free) on my computer and CCleaner won't install.  I have been without CCleaner since June and no one at CCleaner has been able to solve the problem. 

I tried all of the fixes that the moderators mentioned - but nothing works.  If I can't get the free version to install on my computer why should I buy the darn thing?

One idea - I remember not too long ago Windows 10 having issues with Avast AV (which I don't use) and PC's that use ASUS hardware (which I do - motherboard, wi-fi router, monitor, etc.).  Did Avast sneak something into CCleaner that is causing more Windows 10 issues?

Is it just CCleaner that has been affected?

We had a user last week report that 7 apps had stopped running following the Windows update to version 2004.
After a day or so they all started working again.

These days when Windows updates it downloads the needed files, but it may not install all of them for a day or so. (Especially if you turn your machine off following an update).
If you leave your machine on and keep an eye on task manager following an update you can see that the system is still working/updating in the background for as much as a couple of hours afterwards.

 

I haven't switched to 2004 yet - I have Windows 10 Home Version 1909.  I don't allow Windows to automatically install updates - I do them manually.

It is just CCleaner that is crashing.  I uninstalled Norton and still had the same problem with CCleaner not installing.  I took it to the PC shop where I bought my PC and the tech was able to get CCleaner installed again for a service charge fee, but it crashes when you try to Scan/Analyze the PC or go to Options > Cookies.  Anything else and doesn't crash - I can check my registry, etc.

I gave up and figure Avast must have done something to CCleaner and I've switched to [COMPETITION] temporarily until someone can figure what to do.

Thanks nukecad for suggestions I tried them all - including the "other possible solutions when CCleaner won't install".

I tried ccSlim & ccPortable with no luck.  It tries to install CCleaner & ccSlim but closes at about the 92% point. ccPortable installed but wouldn’t run – it seems to have issues with the new Health Check, which must be a new feature Avast tried to add.

I have Windows 10 Home Version 1909 and run Norton 360 as my virus/firewall protection. Windows Defender isn’t used other than the occasional virus scan

I installed Windows 3 updates on 6/2/2020 (CCleaner v5.67 ran fine on 5/31/2020):

1 – KB4497165: Intel microcode updates
2 – May 12, 2020-KB4552931 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903 and Windows Server 1903 RTM and Windows 10, version 1909 and Windows Server, version 1909
3 – May 12, 2020—KB4556799 (OS Builds 18362.836 and 18363.836)

I was running CCleaner v5.67 without a problem until the 6/2/2020 Windows Update.  I uninstalled v5.67 when it wouldn't run and then tried to reinstall - with no luck. I even tried to install v5.66 without any success.

I tried turning off Norton 360 – which says CCleaner is an approved software (it has a bunch of different CCleaner software approved - CCleaner, Ccleaner64, CCslim, CCportable, etc.).  I'm not sure if I should remove all of the approved CCleaner software from Norton and let it start fresh or not.  I also excluded CCleaner from both Norton and Defender – with no success.

I updated Windows 10 earlier this week based on 2020-06-02.  I just tried to run my CCleaner for the first since then today and it won’t open.  I rebooted and it still won’t open.  I uninstalled and reinstalled and CCleaner won’t install.

Did MS – in their infinite wisdom – change a setting again like they in so many recent Win10 updates – that is keeping CCleaner from opening??   It worked perfectly fine last weekend when I ran it – before the most recent Windows update.

All of my other virus, cleaning software works fine – Norton, Malwarebytes, SuperAntiVirus, etc.

Thanks
