Hello,
I can't install Esenthel Engine, the installer alert me that ,
I tried it many times and fails again. Is there exists an offline installer please? Thank you for any help if you can provide.

Hey you can always install in the pc that you got your net connection and then just copy the "Esenthel" folder.

You'll also need visual c++.

Hi,

If you have internet access but still getting that error, it may mean your firewall is blocking the app, please make sure to whitelist Esenthel on your firewall.
