Troubleshooting Windows 7 SDK Download/Install

This article applies to the Windows SDK for Windows 7 and .NET Framework 3.5 SP1.  Read these other posts to troubleshoot issues with the Windows SDK for Server 2008 and .NET Framework 3.5 or to troubleshoot issues with the Windows SDK Update for Vista and .NET Framework 3.0.  

The Windows 7 SDK is available for download in ISO or Web Setup format.  Web setup allows you to select a specific subset of the SDK so you do not have to download the entire SDK. The ISO setup allows you to download the entire SDK to burn to disk or a virtual drive, and install later. This release provides three platform-specific ISOs.  Choose the ISO that matches the CPU platform (x86, x64, or Itanium) that you are installing on.  If you are having problems downloading the correct ISO from the Microsoft Download Center, use these direct links:

Running the Windows SDK web setup on some connections can sometimes have issues when downloading the files. We recommend that you clear the %temp%\sdksetup directory and retry your web setup. If that fails, switch over to the ISO setup for the Windows SDK. 

Typical %temp%\sdksetup directory:

On Windows Vista or Windows 7: C:\%user%\AppData\Local\Temp\ SDKSetup_7.0.6918.0.log
On Windows XP: C:\Documents and Settings\%User%\Local Settings\ SDKSetup_7.0.6918.0.log

About ISO image files

Many products are posted as ISO image files.  An ISO file is an exact representation of a CD or DVD, including the content and the logical format. ISO files end with an .ISO extension.  The most common use of an image file is to write it to a blank CD-R or DVD-R. ISO image files can also be opened and their contents copied to a local folder, much like ZIP files. ISO files may also be virtually mounted and accessed as a device. These two methods of using ISO images are described below.

Copying the contents of ISO files to a drive

The contents of image files can be used as virtual discs using utilities such as ISObuster, Daemon Tools or Virtual CloneDrive for Windows. Using this method you can extract the files from an image file to a temporary folder on your hard drive, then run setup.

Writing ISO files to CD-R or DVD-R

Most CD-R/DVD-R writing software includes a feature to create a disc from an image file. Note: you must use the special “copy image to CD” or “burn image” functionality. See your software’s Help for detailed information. Common utilities for writing ISO file to recordable media such as DVD-R include Nero and Roxio. In Windows 7, you can burn and ISO by right-clicking the .iso file and selecting “Burn disc image”.  After a CD/DVD-R has been written, you should verify that the file was successfully written. Many freeware programs are available for calculating the SDK SHA-1 hash value.  Use an Internet search engine to search for “sha1 hash” to find a freeware program.  Windows SDK for Windows 7 verification information:

    The x86 ISO setup program needs to have an upfront check to catch attempts to run it on an x64 version of windows.

    Currently it lets you select the destination and components to install before aborting with a failed to find WinSDK_amd64.msi error message.

    Not at all clear!

    I also had the WinSDK_amd64.msi error message and after 3 weeks I finally figured out that I needed to upgrade Visual Studio to SP1. I was trying to install SQL Express 2008 Management Studio and it needed VS SP1 in order to install. That got me thinking about the SDK again. Anyways, after I upgraded VS to SP1, I reinstalled the SDK and it worked the first time.

    I did not find any info on this subject, so I hope this helps others!

    It’s wierd that I do not get the option to download Visual Studio SP1 in Microsoft updates. I had to go to MS downloads to get it… I did however get the 500+mb worth of security updates after I installed the service pack.

    I got the error message when installing:

    Setup could not find the file WinSDKWinSDK_x86.msi at any of the specified source locations E:Setup

  4. SmartBye says:

    When I try download this .iso file it throw error – "404 NOT FOUND". Where I can download this?

  5. WinDSK_x86.msi says:

    Pardon?  Are you looking for me?

    When you install I am not in the E:Setup folder.

    Do you know where I am?

  6. Soniya says:

    Setup could not find the file WinSDKWinSDK_x86.msi at any of the specified source locations ….

    m i the only one who is still facing this issue…

    is there any workaround for this issue…

    P.S : i dont want to take the pain of downloading the huge iso image..

  7. norman says:

    I got trouble downloading win7 sdk (1.4GB ISO), it always disconnected, even though it already at 99%. Can we download from elsewhere? like torrent or split file?


  8. Eldar says:

    I'm trying to uninstall Windows 7 SDK and a window pops up with the error message saying that "WinSdk_amd64.msi" does not appear.

    Now, I find it very strange that the product itself does not contain all the necessary files needed for its uninstallation. However, I also tried to uninstall using winsdk_web.exe. But, this setup utility could not find this file as well and did not even try to download this file from Internet.

    Do you know of any solutions for this specific issue and do you plan to improve install experience in general in the future Visual Studio and Windows SDK versions?

  9. I tried to install Windows 7 SDK but my installation fails. Log file is here:…/SDKSetup_7.0.6918.0.log
