Visual Studio 2010 Service Pack 1 and Windows SDK for Windows 7 and .NET Framework 4 Issue

Microsoft has identified an issue for users of the stand-alone Microsoft Windows SDK for Windows 7 and .NET Framework 4. Currently there is no workaround to enable installation of the Visual Studio 2010 Service Pack 1 for these users.

We recommend that users of the Windows SDK do not install Visual Studio 2010 Service Pack 1 at this time. We are currently working on an update to fix this issue and will update this page when it becomes available.

Issue

If you have downloaded and installed the stand-alone "Microsoft Windows SDK for Windows 7 and .NET Framework 4 (Windows SDK v7.1)" and you are using the x64 or IA64 compilers that were included in that download, you may find that these compilers and the associated Visual C++ library files removed. The impact may be as indicated below:

· If Visual Studio 2010 Professional is installed, then the IA64 compiler and Visual C++ libraries are removed.

· If Visual Studio 2010 Express (any edition) is installed, then the x64 and IA64 compilers and Visual C++ libraries are removed.

· Visual Studio 2010 Premium and Visual Studio 2010 Ultimate are unaffected.

Please see this article for more information about Windows SDK v7.1 with Visual Studio 2010 Service Pack 1 – Potential issue with x64/IA64 Visual C++ Compilers.

Please see this article for more information about the issue, and how to restore the SDK compilers to a working state.
