Hi @motto5476,
Thanks for sending the msi trace.
We are currently, analyzing it.

Run the “MicrosoftProgram_Install_and_Uninstall.meta.diagcab”, select Installing.
If “spacedesk Windows DRIVER” is not on the program list, just select “Not Listed” then paste the product code of spacedesk_driver_Win_10_64_v1040_BETA.msi here: {A7749853-C2A7-4313-B46F-11AECF983D62}
After that, please reboot your primary machine then try again to install the latest spacedesk msi installer from the website.
