License activation in offline (no network)

License problems
1

First, thank you for developing eM Client.
I’m free license user, and I want to activate license in my local network environment (no external network).
I tried to activate eM Client license, but the error message box was popped up.
“ActivateLicenseFromApplicationEx failed”

Please help me.
Thank you.

Hi Seung,
unfortunately, eM Client needs to be connected to the internet (online) to be activated and needs to connect to the licensing server once every 14 days at least to continue working, otherwise, the program will turn to and work only in offline mode.
