Offline users - A way to update expiration date
BernardoI will need to update some licenses monthly. I these licenses work offline, so each update demands few steps (the client generate a file, send a file, a receive a file, generate the response, send the response, the client validates his license).It would be great i I could them monthly, an response file with the updates. Is this possible?
