At my company I need to go through a proxy to get online and the installer doesn't seem to pick up the default IE proxy settings (or firefox one) and it is failing. I haven't seen any way to specify it via command line either. So please fix it or provide a full SDK download. Thanks. https://sourceforge.net/p/necessitas/tickets/51/
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years and I will be closing this bug.
