You might need to reboot your machine first. could you please reboot your machine and then try again with the installation?
if the issue persists, could you please provide us with the following files?
– 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 in your next reply.
There may be a conflict with your destination folder causing the failed installation. Could you please try installing it in a different folder? Also, make sure not to put any spaces between the folder name.
Please refer to the attached screenshot for assistance.
If it still fails, please resend us the required files.
We have released a new spacedesk Driver v2.1.09 on the web. this includes a potential fix for the install issue you encountered.
To test this, just install the MSI and do not change the default destination folder (Program Files).
We look forward to your feedback!
