So in case, the CCleaner Installer is not working on your Windows 10 PC, then you could try out the aforementioned builds as well. So tonight I downloaded the latest ccestup569.exe and ran it on a test Win10 PC using the 'customize' install option. After I upgraded my old Win7 to Win 10, Ccleaner stopped working. You could directly access the app by launching its EXE. It is why I froze my Ccleaner version on Windows 7 a few years ago. On the other hand, its portable build doesn’t need any installation. The first one is a trimmed down version of the app and only has the absolutely necessary components. CCleaner also comes with Slim and Portable Builds.

However, if you still face some issues, then you could try out another variant of this app as well.

Once installed, launch the app and then update it from within the app itself. If the current version of the installer is causing some issues, then you could also install an older build of this app.

Click Apply > OK and check if the CCleaner Installer not working issue on Windows 10 has been fixed or not. Install free third-party utility, such as CCleaner to clear the junk from the system cache that includes fixing by breaking the registry error, which is very useful in correcting different problems that include AMD Radeon Software has stopped working'.

Enable the Run this program as an administrator option.

To do so, right-click on the installer file and select Properties.

If the group or individual user profiles aren’t given the required permission to deal with setup files, then those set of users won’t be able to carry out the installation.

Once done, reboot your PC and then check if it fixes the CCleaner Installer not working issue on your Windows 10 PC.

However, if it isn’t there, then click on the Allow Another App button, navigate to the app’s installation directory and select it.

Select the app from the list and hit OK.

You will need administrative privileges to carry out this task.

Then click on Change Settings from the subsequent dialog box that appears.

On the other hand, if you wish to add the app to the exclusion list, then click on Allow an app or program through Windows Defender Firewall.

Next up, enable the Turn off Windows Defender Firewall option under both the Public and Private network sections.

Then select Turn Windows Defender Firewall On or Off from the left menu bar.

To begin with, search for the Windows Defender Firewall from the Start menu.
