Can't uninstall CCleaner.

Recommended Posts

Hello,

I'm not sure what caused this - I can't uninstall CCleaner. When I try to do that, I get the following message: "NSIS Error - Error launching installer."

I am using the free for home use version, build v5.61.7392.

Open Task Manager and EndTask any running CCleaner processes, then try the uninstall again.

If that doesn't help perhaps uninstalling it by a different more robust means will work with either of the two freeware uninstallers linked below. Both do the same task by scanning for leftover files, folders, registry settings, and remove as much as they can. You may need to restart your computer after using them.
* Geek Uninstaller Free
* Revo Uninstaller Free

Hello,

Thank you for your reply, Andavari.

No luck with the task manager.

I was familiar with Revo. Unfortunately, neither Geek nor Revo uninstallers managed to fix the error. They do find some remaining files (I doubt they find all of them, though) and they do appear to remove them, but once I download CCleaner from its site again, install it and try to run the uninstaller, I'm getting the same NSIS error.

Should I go back to some older versions of CCleaner? Or that won't solve anything?

I'm lost here. Don't recall having such trouble with uninstalling CCleaner ever before.

Might help to mention what operating system you're using, and if you have administrator privileges on the account you're using - that's about all else I can think about at the moment.

Have you tried using CCleaner itself to uninstall CCleaner (under Tools > Uninstall in the CCleaner console)?

Yes, I have.

It's giving me the same error.

XP SP 3.

So... quite ancient, I realize that. 

But this is the first time I'm having trouble uninstalling CCleaner (I've been using it for years on many operating systems) - and as far as I know, Piriform still makes sure their products are fully compatible with XP.

While Piriform products are still compatible with good ole charished XP SP3, that might not necessarily be the same for the NSIS installer/uninstaller they use.

With the way CCleaner installs which is minimal by my books by not creating a bunch of stuff all over the system in files and registry settings I'd be rather confident in the abilities of both Geek Uninstaller Free and especially Revo Uninstaller Free removing it after a reboot in case Smart Cleaning ("used to be called Monitoring") is enabled in CCleaner -- even though the default built-in NSIS uninstaller is failing.

I thought not too long ago someone else reported a failure of it uninstalling, can't seem to find that topic. Maybe the uninstall failure has something to do with Smart Cleaning if it's enabled on the system, since it causes so many failures to merely update/upgrade CCleaner with it running resident in the background.

Only with its security level set to the minimal.

You might be onto something here... I'm going to uninstall it in a few days.

I see.

Yeah, Revo seems better.

Thanks for letting me know, I may look for the thread later.

Major update: I managed to fix the problem by reverting to the old version - build v5.59.7230.

In v5.60 we upgraded to a newer version of Visual Studio, this appears to have caused some compatibility issues with XP however, they only appear to be related to the newer installer UI.

If you do want the latest version of CCleaner you can install it successfully on XP with the Slim version of the installer, this can be found here - https://www.ccleaner.com/ccleaner/builds

Thank you, it worked like a charm.
