I am running a Windows Server 2008 R2. I would like to install italian as another display language, so I downloaded the Multilingual User Interface iso file with a lot of locale packages included. However, when I try to install the language pack (Install/Uninstall display languages) I see the following screen telling me that the languages cannot be installed:
UPDATE: We are using volume licensed software and we have only the single language system, so there is no way to have multiple languages. However, is there a way that I can change the system language? I dont need english.
