Activation with proxy, settings not saved

Hello, I work as a software packager.

We have lockeddown clients and when i have installed Draftsight and need to activate it does not work.

I have tried to put in the Proxy settings and then restarted the program but no luck. And when i go into the settings for Proxy again it is empty again. Someone knows where this will be saved, in the registry or in a file? And where this settings are then? Need to know this because maybe i need to assign more permissions regarding this.

Thanks in advance
