Thank you very much for sending the logs. We are currently analyzing it.
For further analysis, could you please download and extract the zip file here: https://www.dropbox.com/s/rqayx759wdwmye2/msi_trace.zip?dl=0
Inside the folder, please copy the most recent spacedesk MSI installer (v1.0.37) then run the get_trace.bat script file.
The script will execute the msi installer (to reproduce the installation error) and will automatically generate a spacedeskmsi_trace.txt file, then please send the file to us after executing the failed msi installer.
