I've been trying to install Microsoft .Net Framework (ver. 3, 4 and 4.5), but gets an error everytime coded "HRESULT 0x8000222". Now as far as I could find out, this refers to a problem with Windows update.
My internet connection works (since I'm writing this now on the internet connected), but the button at the task bar icons shows it to be ofline (or not connected). When I try to run windows update it tells me: "Windows Update cannot currently check for updates, because the service is not running." despite the fact that the settings is on "Always check for updates".
