Trial period expired

Hi, have been trialling the hyperv client with moderate success and reliability. Basically very happy with how it runs.
Can someone tell me how to tell if the trial period has finished? And also how to tell if licensed once purchased.
I have a few servers running and trying dif con figs in a lab along with production environments.

Thanks for you interest!

It stops backing up and on the status screen in the status column it’ll show “trial expired”.

The client version column on the status screen shows something like 2.2.20-hyperv.
