This post is
to explain how to fix the "Unable to start Setup. Please check your
installation media and try again" error when installing the Server VDA
with Desktop Flag.
During the installation of the VDA the below error comes up
Check the VDA install log (xendesktop installation.log) in this location
You'll see the below error in the log "Server VDI cannot be installed if Windows Remote Desktop Service Roles are installed"
Remove the Remote Desktop Session Host Role and reboot the VM.
Once the VM is rebooted attempt the installation again
The Remote Desktop Session Host role is installed and it can't be present for a Server VDI VDA installation.
