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).
I had the same problem with my Visual Studio 2010 Premium, also on a German Windows 7 64 bit. After several hours I managed to install the Service Pack 1.
The problem is that the setup requires Visual Studio Tools for Office to be installed on x64 machines. So customize your Visual Studio 2010 Installation via the control panel (add/remove programs) and add the feature "Microsoft Office Developer Tools (x64)". After adding this feature, you will be able to start the SP1 Setup.
