I have a deep look into your error log file, and I found that you get the following error message:
Windows SDK Setup (failed): Installation of the "Microsoft Windows SDK for Windows 7" product has reported the following error: Please
refer to Samples\Setup\HTML\ConfigDetails.htm document for further information.
Stack: at SDKSetup.Product.ConfigureNewProduct(ManualResetEvent CancelEvent)
at SDKSetup.Product.SetupProduct(TaskMode taskMode, ManualResetEvent CancelEvent)
at SDKSetup.ProductCollection.SetupProducts(TaskMode taskMode, DownloadManager downloadManager, ManualResetEvent
at SDKSetup.ConfigProducts.DoCurrentTask(TaskMode Task)
So could you please also upload the \Setup\HTML\ConfigDetails.htm as well?
