Hi @santiiju2,
Could you please check if there are pending Windows updates in your system settings (or your current update may be lacking some important packages.) If there is, please try to update them and try again with spacedesk.
If that didn’t solve your problem, could you maybe try the suggestions found on this website?

in case the Issue persists, could you please resend us your spacedeskSetup.log together with the following files:
– Run dxdiag.exe on your primary machine, click “Save all information”
– setupapi.dev.log file located in C:\Windows\INF
Please save all requested files in one folder, then right-click -> Send to -> Compressed (zipped) folder, then attach the *.zip file in your next reply.
in case it exceeds the allowed size, send it to us by uploading it to any cloud storage app like google drive or dropbox and send us the link.
