"I disconnected my internet, turned off Kaspersky, installed InstallLicense.342032302032323033.1.exe"
Without a connection to our site, InstallLicense.exe cannot download and install the license server, it just prints an URL that you have to download at another computer with Internet connection, then execute the downloaded file. Did you do that?
The Manager cannot connect to the license server, so it is either not running or not even installed. You can check that you have "Ephere License Server" in your Services, with Running status and Automatic startup.
