CCleaner won't open on Windows on ARM (Surface Pro X) PC


Recommended Posts

Hi,

Version: 5.76.8269
Windows 10 20H2 (OS Build: 19042.804)

I don't know if it's only with this version as I've only just noticed the issue, although it used to open fine. On my Surface Pro X CCleaner opens in Task Manager for a second then disappears. Nothing shows on screen and there are no errors.

Oddly when the app doesn't load a file called gcapi_16133347499292.dll appears in the installation folder, this disappears when it loads correctly:

I tried uninstalling CCleaner, deleting the installation folder and reinstalling it.

I've tracked it down to CCleaner suddenly not being compatible with WoA default x86 emulation settings. You need to tick Disable App Cache in Compatibility Settings and then it loads fine:

 

Disable application cache

The operating system will cache compiled blocks of code to reduce emulation overhead on subsequent executions. This setting requires the emulator to recompile all app code at runtime.

This isn't ticked as standard.

Can this be investigated?

The Surface Pro X has been out since October 2019. I'm not expecting an ARM64 binary but why aren't Piriform still testing CCleaner for Windows on ARM compatibility?

Thanks

p.s. I only use the Custom Clean section.

Still looking for a solution to loading CCleaner Pro onto a Surface Pro X. I can see that bradavon was able to find a work around by unchecking a cache button in the properties, but how do you get the CCleaner properties to open if the program isn't loading to begin with?

Apologies I could've been cleared. You don't do it in the app but either of these places:

  1. Right Click on the CCleaner shortcut on the Start Menu -> Properties -> Compatibility tab
     
  2. Go to -> C:\Program Files (x86)\CCleaner -> CCleaner.exe file -> Properties-> Compatibility tab ->

  3. Then set it as I show in the screenshot in my original post.
  4. CCleaner should now open. I've not seen any difference changing this.

Update:

Retested with the latest release build: 5.79.8704

You still need to do this. I've just put the Compatibility tab for CCleaner.exe back to defaults and it's exactly say as it was when I posted it in February. But as no one's replied to the thread I'm guessing it's not been looked at yet?

Thanks

I gather that Microsoft's support for 64 bit applications on ARM devices is still a work in progress: https://www.techrepublic.com/article/windows-on-arm-this-is-how-well-64-bit-emulation-is-working/ - but I note that this is the 32 bit version that you are running.  I'll see if support has had similar cases.

Hi Dave,

Thanks. As I don't believe CCleaner officially supports Windows on ARM I only use the Custom Clean feature. I wouldn't trust the Registry feature yet. Correct the 32-Bit version.

I didn't know there was a 64-Bit CCleaner though?

Windows on ARM 64-Bit AMD64 App support is out in Windows 10 Insider builds. Microsoft haven't said when it's going to RTM but I'm hoping by the end of the year. I can't use a couple utilities I used to use, but otherwise I'm using the same apps I did on my (Intel based) Surface Pro 4.

Currently ARM (32-Bit and 64-Bit) + 32-Bit x86 apps are only supported though yes.

Thanks for passing it to Support. It's going to be much slower on Windows than MacOS but Microsoft will only continue to develop Windows on ARM.
