This might be a problem with my setup and not with the beta version. Very likely it's the same issue which I have already asked about in https://www.displayfusion.com/Discussions/View/displayfusion-suddenly-has-problems-with-ssd-access-rights/?ID=019234e0-ffb8-77c0-b66f-3c186e4377b2.

But after installing the beta version I'm at least able to start logging and provide log files. So here goes.

When clicking on 'Desktop Wallpaper' in the 'Options' tab, DF shows this error:
"An error has occurred while loading the Wallpaper Settings.
Failed to call CreateWebViewTHROWS.
Schwerwiegender Fehler (0x8000FFFF (E_UNEXPECTED))
[System.Runtime.InteropServices.COMException]
[System.Exception]"

Attached the export from the 'Troubleshooting' tab. I copied the DisplayFusion.log into the zip file as well.

Thanks in advance,
Christian

I installed Version 11.0 (Beta 7) again and tried the settings you recommended. Same result after reboot.
But only in restricted windows accounts. Not in admin accounts.
