Hi @muller,
Did you recently updated your Windows operating system? This error could possibly be the result of a pending reboot flag. Have you already tried rebooting your primary machine? If so, does this error still appear consistently during the installation/upgrade of the spacedesk Driver?
For further analysis, could you please send us the following:
– run dxdiag.exe on your primary machine, click “Save all information” and send us the output file
– spacedeskSetup.log file located in C:\Users\Public
– 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 on your next reply.
