Hello,

I'm downloading from this page by clicking this link http://go.microsoft.com/fwlink/p/?LinkId=526740 at the very bottom, and then running adksetup.

No matter what I chose to install or download, I get "An error occurred while downloading Documentation" on several PCs from several different ISPs

The logs

The logs reflect several retries with the same result (the last attempt is shown above). 

Please address the issue.

Thanks,

I too am having the same problem. There must be a problem with the content as I've tried from many different network configurations.

Thanks

I just tried on both my Windows 7 system and my new Windows 10 Preview.  No matter what options I choose, I get the same error.

My preferred method that I tested most was to download the files to install onto another computer.  The progress bar never moves anywhere, and the software mentioned Documentation as what it was trying to download when it errors out.

Hi,

It seems like there is a problem with ADK file, please be paint and waiting for this problem fix.
