This error which occurs when trying to install Net Framework 3.5 prevents me from installing ANY new windows features I have install and updated Windows 10 1511 build 10586.3. For what its worth it occurs in all previews builds of Windows. It is maddening because I cannot install Direct Play - required for many programs.

The displayed error references a link which only applies to Windows 8/8.1 and the Error Code 0x80071A90 is NOT listed in the article.

This is a very serious bug and I need to know how to fix it. And yes I have used the offline Windows Framework 3.5 installer from the boot media - didn't resolve the problem
