Inventor 2015 Browser Process Error

[Gongalong]

Hi folks,

 

I've created a test deployment on our student PCs of Inventor Professional 2015.

 

When Inventor launches the browser appears to crash, and then I get a warning dialog which says:

 

"The browser process exits unexpectedly. Please check:

 

1) You have internet connection;

2) Firewall blocks starting the browser process AdCefBrowser.exe;

3) Firewall blocks browser process AdCefBrowser.exe to access Internet;

4) Proxy setting in Preferences - > Network.

 

Do you want to try connecting internet again?"

 

The Windows firewall is disabled, but we do use a proxy server. Except that I cannot find any preferences dialog that references network settings.

 

Does such a dialog exist, and can someone explain where I access it from?

 

TIA
