Unable to launch Snowrunner

[Snappy447]

The result I get from running the command to launch SnowRunner (App name shows as Mayflower) results in

Legendary launch Mayflower

[cli] INFO: Logging in... [Core] INFO: Trying to re-use existing login session... [cli] INFO: Checking for updates... [Core] INFO: Getting authentication token... [cli] INFO: Launching Mayflower...

It seems to launch to a black screen, then hang for a couple of seconds and then close gracefully

I have previously run
E:\Users\Scott\Downloads\legendary>legendary install Mayflower updates
