Hi @nosotrospapaya,
could you please open the device manager (just run devmgmt.msc) on your primary machine, click View tab -> select Show hidden devices and Devices by connection.
Find any spacedesk virtual devices below, if you find spacedesk virtual HID device, and there are devices underneath it, please right-click uninstall all devices one by one then uninstall „spacedesk virtual HID device“ last.
By the way, please delete the old spacedeskSetup.log file, the file size seems too big now.
Then try again with spacedesk installation.
