CCleaner doesn't work on this version of Windows (portable version, run with /auto)

[steje]

I see several threads here on the forum about this - but most have to do with INSTALLING CCleaner - and don't seem to apply to the issue I'm reporting here.

 

I completely wiped all partitions from my disk (SSD) and re-installed Windows 10 build 1607 (Anniversary Update) clean from the latest USB image created using the Media Creation Tool on 12/17/2016.

 

After the base install was complete, I was able to run the PORTABLE version of CCleaner Free v5.25.5902 using the ccleaner64.exe /auto command line option from a batch file bound to a hotkey. CCleaner woirked fine across a few reboots.

 

After that, I ran a WSUSOFFLINE update built from the base install off of the USB. It installed a few updates, but there were still a few more using Windows Update. After the online update, my Win10 OS is now at Version 1607 and OS Build 14393.576. Since completing these updates, trying to run ccleaner64.exe /auto now causes Windows to throw the error:  "CCleaner doesn't work on this version of Windows". But the app STILL WORKS if I launch it manually (withOUT the /auto command line option) and use it via the GUI.

 

Any thoughts on how this can be resolved? I know WSUSOFFLINE does some things to disable UAC temporarily when selecting the "Automatic Reboot and Recall" option, but it appeared to clean up after itself properly and UAC seems still set to the Windows 10 default.

 

Any idea what can be done to resolve this? Using the GUI isn't a horrible short-term workaround, but I hope someone can figure out how to get the unattended command line to work again SOON.
