I got it, I'll do the following:



  • in control panel -> internet options -> privacy -> settings -> blocking level: make it low
  • go to this link: http://www.microsoft.com/download/en/confirmation.aspx?id=17851 and install the .NET Framework 4.0 web installer version, there is something with the windows installer that allows you to install the offline version on Windows Server 2008 R2

Back again ...

Seems like the simple answer is that you are not downloading stuff on Windows 2008R2. Use your workstation to download the files and then copy them to the server OS.



Here's a quote from https://serverfault.com/questions/175924/enable-downloads-on-windows-server-2008-r2 :

It's a pain in the rear, isn't it? This is a deliberate choice on the Microsoft side. There are ways to enable download but not recommend it. No matter how confident you are of your reputation, the website you visit is the OS of the server and you shouldn't use it to browse the internet even to download patches, installers, etc. Instead, use your workstation to download and then copy the files up to the server for installation.
