The new license system requires an internet connection to obtain the license key, so you need to be online when starting the simulator for the first time.
The expiry for this beta version is 30 days after installation (instead of a fixed date as earlier). If we need to extend the beta testing period further, you will be granted a new 30 days beta license.
In addition to the license management, the update contains some small bug fixes and improvements.
The update can be found on the Download Page.
