I have exactly the same error and cannot find any others error logs
Note: I have tried to downgrade to latest 4.3.30 and got also an error
Do you also have the same error while downgrading?
Hum, if I set the compatibility to "Vista SP2", I can start the client, but I'm not able to start any VMs, even create a new one
