Hello,

today I noticed that DF 10.1.2 on Windows 10 seems to have problems changing the wallpaper. Trying to open the Wallpaper settings does not work. The settings window does not open.
Trying to restore a backup of the settings works, but with an error message that the wallpaper file cannot be opened.
Trying to backup the settings gives a hint about what's going wrong: I get an error message that the folder location on the internal SSD cannot be accessed. My user folder is offered as an alternative, but that doesn't work either.
It seems to me that DF lost it's access rights to any folder on the SSD.

Further Tests:

My account on the PC is a restricted account and here I have problems.
On the admin account everything works fine. DF has access to the SSD.
Another user has a restricted account on that PC and here DF also works fine. No access problems on the SSD.

Uninstalled and reinstalled DF. My settings were apparently not deleted during uninstall. The problem persists.

Tried the Troubleshooting section:
No information shown in the window. I am not able to change the log setting (L0 - L3). After changing to L3, clicking 'apply', leaving the section and re-entering it, the setting is L0 again. Apparently the SSD access problem also prevents logging.

Last chance:
How can I uninstall DF and remove all settings, in order to do a clean install?
Or does anybody have an idea how to get DF running on my account again?

Thanks in advance,
Christian

I tried to export all settings of all users and found that the other restricted account also has permission restrictions.
Exported all settings to an external disk. The I uninstalled DF and removed all relevant folders from:
- Users AppData folders
- C:\Program Files
- C\ProgramData (Nothing in C:\Program Files (x86))

I went through the registry and deleted all keys relevant to DisplayFusion

Then I reinstalled DisplayFusion: Same problems.

Any other ideas?
