I have installed the German version of Visual Studio 2010 Professional (got it per Microsoft DreamSpark). When I'm trying to install the Visual Studio 2010 Service Pack 1, I get the following message from the installer:
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.
An English translation is:
Can't install SP1, as the actual state of the Computer is not supported.
Does anybody has a similar problem and a solution? My operating system is Windows 7 64-Bit (German Edition).
