This article applies to the Windows SDK for Windows Server 2008 and .NET Framework 3.5. Read this other post to troubleshoot issues with the Windows SDK Update for Vista and .NET Framework 3.0.
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: C:\%user%\AppData\Local\Temp\SDKSetupLog.txt On Windows XP: C:\Documents and Settings\%User%\Local Settings\SDKSetupLog.txt
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 Vista. 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. 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 Server 2008 ISO verification information:
