Part of the problem is that when I start Esimulate, selecting think Schem 3.0, then the window opens normally but on the tab above the application of Esimulate should appear, but do not appear.
If you have correct license file and still can't run Schematics 2.0 try this:
127.0.0.1 <your_machine_name> (there is a space between IP address and machine name)
Save hosts file and exit. It should work then.
What you're doing that way is simply tell the license mechanism that a computer with IP 127.0.0.1 (it's a loopback IP for localhost) have also a name <machine_name>. Thanks to that information Schematics will look for the license in the license server running on your local machine.
Try using server IP address in PSF instead of server name (replace RATENCI0 with server IP)
