Thank you very much for sending the requested files.
It seems that uninstalling the old spacedesk HID driver is hanging.
This is a known issue in our older version, as a work around, please try to manually uninstall the old spacedesk Driver version on your primary machine before installing the latest version 1035.
For assistance, please check Uninstall on Windows Primary Machine -> Manual Uninstall (Troubleshooting Only) chapter in the user manual. https://www.spacedesk.net/user-manual/#item_518
PS: Please make sure you do the Step 4: Uninstall spacedesk virtual HID Device (for Windows 10 only).
By the way, before you uninstall manually, could you please tell us the old version currently installed on your primary machine?
