title: Microsoft Visual Studio 2010 Service Pack 1 Installation
body: <p>I have installed the German version of Visual Studio 2010 Professional (got it per <a href="https://www.dreamspark.com/" rel="nofollow noreferrer">Microsoft DreamSpark</a>). When I'm trying to install the <a href="http://www.microsoft.com/downloads/de-de/details.aspx?FamilyID=75568aa6-8107-475d-948a-ef22627e57a5" rel="nofollow noreferrer">Visual Studio 2010 Service Pack 1</a>, I get the following message from the installer:</p>
  
  <blockquote>
    <p>Microsoft Visual Studio 2010 Service Pack 1 kann nicht installiert werden, da es vom aktuellen Zustand dieses Computers nicht unterstützt wird. Anweisungen zum Beheben des Problems finden Sie in der Infodatei auf der Microsoft Download Center-Website.</p>
  </blockquote>
  
  <p>An English translation is:</p>
  
  <blockquote>
    <p>Can't install SP1, as the actual state of the Computer is not supported.</p>
  </blockquote>
  
  <p>Does anybody has a similar problem and a solution? My operating system is Windows 7 64-Bit (German Edition).</p>
