I found an intermediate solution.
You need to create * .bat script and inside:
msiexec / i C: \ spacedesk_driver_Win_10_64_v1018_BETA.msi / qn / norestart
(The installer can be on a flash drive)
With some programs, we change BAT to EXE (in Invisible mode – do not show the window) and name it e.g. spacedesk.exe
(Unfortunately, many antivirus programs treat the file created in this way as a threat and try to block it. You need to find one that at least bypasses Windows Defender. You can check this on the VirusTotal website)
Click on the spacedesk.exe file with the right mouse button and select „Run as administrator“ from the menu.
You can also select Compatibility in File Properties and Run this program as Administrator, but when run this way, a little info window pops up.
