winapi – Windows 7 SDK installation failure

Microsoft now has a knowledge base article called Windows SDK Fails to Install with Return Code 5100 that describes this problem and its fix:

This issue occurs when you install the Windows 7 SDK on a computer that has a newer version of the Visual C++ 2010 Redistributable installed. The Windows 7 SDK installs version 10.0.30319 of the Visual C++ 2010 Redistributable.

The error message is located in the log file, which can be opened through the View Log button in the installer. Otherwise, it can be found here: %userprofile%AppDataLocalTemp or %temp%. The log file is most likely called SDKSetup_7.xxxxx.log.

Solution: Uninstall any existing Visual C++ 2010 redistributable.

I just had this problem, and I looked at the solution at Ctrl+F5, Fix Problem Installing Windows SDK for Windows 7, but it didnt work.

I googled around and found the page Installing Visual C++ 2010 and Windows SDK for Windows 7: offline installer and installation troubleshooting and the advice there worked. Basically you could have one of several problems, and you have to look in the log file to see whats going on. In my log file I had:

6:17:07 PM Saturday, October 01, 2011: C:Program FilesMicrosoft SDKsWindowsv7.1SetupSFXvcredist_x64.exe installation failed with return code 5100

so as that above web page suggested, I uninstalled both copies of the Visual C++ 2010 Redistributable Package that I had (both x86 and x64), and then when I ran the Windows 7 SDK installer again, it worked.

Although you might have a different problem than me. Try the solutions at the Ctrl+F5 and patheticcockroach.com websites that I linked.

I hoped this helped!

All of these (and other) solutions have failed completely for me so I figured out another.

You need the offline installation package (mine was x64), and you need to manually install only the samples. Opening the ISO-file with, for example, 7-Zip from location SetupWinSDKSamples_amd64 and running WinSDKSamples_amd64.msi did this for me.

Then you just use the normal setup file to REPAIR the installation and choose whatever components you wish.

You should really check the log. It seems that quite a few components can cause the Windows SDK installer to fail to install with this useless error message. For instance it could be the Visual C++ Redistributable Package as mentioned there.
