Forticlient VPN v7.0.7.0345 import configuration file unavailable

Hi team,

We use Forticlient VPN v7.0.7.0345 (free version) and I don't be able to import conf file: Restore Bouton is not clickable..

It's the same with the command line executable FCConfig.exe.

So, is it possible to import *.conf file with this version of program ? or this feature are only available in paid version ?

Thanks in advance

PS: Export to *.conf file is available.
And I try to deploy Forticlient VPN configuration through inTune...
