For clarification, did you get blue screen of death (BSOD) crash during spacedesk installation? or upon viewer connect?
For further analysis, could you please send us the following:
– run dxdiag.exe on your primary machine, click “Save All Information”, save the output file (dxdiag.txt)
– most recent dump file (*.dmp) of your BSOD with spacedesk which is located in C:\Windows\minidump folder.
– 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 in your next reply.
By the way, we moved your post to a separate topic to avoid confusion.
