User gets a new Windows 10 machine, installs the SL client and can log into SL, but can’t launch any screen as they all crash immediately.
The issue seems to be that a registry entry that needs to be present has not been created. If the user is not part of the local Administrators group on their machine, the registry key can’t be created.
Add the user to the local Administrators group on the machine, reboot, log into SL, load a screen (successfully), take user out of the local Administrators group if desired, reboot. This will allow the registry key to be created and SL should work properly moving forward.
