Connection Client over Proxy

Hello,
i have a lot of problems with the current "Connection Client" to connect over our internal proxy with username and password.
Your manuals doesn't work or help.

So I spend a lot of time to become your complicated licensing products running...

Is there a possibility to enter the proxy settings with commands / program switches for the current user ?

Are GPOs available for this for example ?

The keys under "HKEY_CURRENT_USER\Software\Bentley\LicenseService" doesn't work when other users sign in, specially the encrypted "ProxyPassword"

Users also work sometime at home (without proxy), Does here a solution exist ? (Our users are not able to modify the settings by themself everytime they switch)

Why does the program not use the systemsetting like every other program can do ?

Regards
