MSI (s) (E4:7C) : MSI_LUA: Elevation prompt disabled for silent installs MSI (s) (E4:7C) : Warning: rejected attempt to add new source 'c:\eb66d60e4283bfc2986755fa\' (product: ) MSI (s) (E4:7C) : Adding new sources is not allowed. What alerted me to the possible error was the following in the SDK setup log: 12:19:42 PM Friday, 8 January 2010: SFX C:\Program Files\Microsoft SDKs\Windows\v7.0\Setup\SFX\dexplore.exe installation started with log file C:\TEMP\Microsoft Windows SDK for Windows 7_dd2d9383-116d-441f-85b3-7c16aeb3568e_SFX.logġ2:19:47 PM Friday, 8 January 2010: C:\Program Files\Microsoft SDKs\Windows\v7.0\Setup\SFX\dexplore.exe installation failed with return code 1625Īnd this in the dexplore installation logfile: MSI (s) (E4:7C) : Machine policy value 'DisableBrowse' is 1 Once the SDK had installed (quite happily this time) I set the value back to 1. What finally fixed it for me was editing this registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer\DisableBrowse as per various blogs and SDKs all to no avail. I uninstalled dexplore, reinstalled it, did a heap of registry changes, etc. It relates (in my case at least) to the dexplore.exe installation. I have had this same problem with the 圆4 version installation. Try the solutions at the Ctrl+F5 and websites that I linked. So as that above web page suggested, I uninstalled both copies of the Visual C++ 2010 Redistributable Package that I had (both x86 and 圆4), and then when I ran the Windows 7 SDK installer again, it worked.Īlthough you might have a different problem than me. In my log file I had:Ħ:17:07 PM Saturday, October 01, 2011: C:\Program Files\Microsoft SDKs\Windows\v7.1\Setup\SFX\vcredist_圆4.exe installation failed with return code 5100 Basically you could have one of several problems, and you have to look in the log file to see what's going on. 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. I just had this problem, and I looked at the solution at Ctrl+F5, Fix Problem Installing Windows SDK for Windows 7, but it didn't work. Solution: Uninstall any existing Visual C++ 2010 redistributable. The log file is most likely called SDKSetup_7.xxxxx.log. Otherwise, it can be found here: %userprofile%\AppData\Local\Temp\ or %temp%.

The error message is located in the log file, which can be opened through the View Log button in the installer. The Windows 7 SDK installs version 9 of the Visual C++ 2010 Redistributable. 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. Microsoft now has a knowledge base article called Windows SDK Fails to Install with Return Code 5100 that describes this problem and its fix:
