Troubleshooting SDK Download/Setup Problems

 Having trouble downloading or installing the Windows SDK?  Here’s help.

Most common issues

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. 

 Also if you are trying to install Windows Vista RTM SDK (build 6.0.6000.16384, released November, 2006), you should try installing the more recent Windows Vista SDK Update (Build 6.0.6000.16386, released in February, 2007):

What are ISO image files and how do I use them?

Many products are posted as ISO-9660 image files. An ISO image file is an exact representation of a CD or DVD, including the content and the logical format. The most common use of an image file is to write it to a blank CD-R or DVD-R, resulting in an identical copy of the original disc including file name and volume label information. ISO image files may 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 three methods of using ISO images are described below.


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.


Testing CD-Rs and DVD-Rs

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 (provided above).  Use an Internet search engine to search for “sha1 hash” to find a freeware program.


Copying the contents of ISO files

The contents of image files may be accessed directly using third-party tools. Using this method you can extract the files from an image file to a temporary folder on your hard drive, then run setup. The following tools (and others) offer image file support:
