Requesting help for Gauss Software.

Hi, this is my first post here, and I'm looking for some help with the use of Gauss Light.

I downloaded the Light version, wich is free for students, but after I put the app file in the applications folder, it request password for start and then it closes.

The only output wich I can get, from the terminal is this.

V-ctor-Mac:MacOS victor$ ./GAUSS
sysctl: kern.tfp.policy: Invalid argument

And nothing else happens.
I follow this webpage to download gauss light.
