Dot net 3.5 install error

I've had lots of issues in the past with being unable to install Dot Net 3.5 on Windows 10.  Typically, I can easily load the Win10 ISO, mount it, and use DISM with the sources switch.  Today I started encountering 2 laptops running Windows 10 that I continued to have issues and errors.

ISO mounted and received "the source files can't be found".  This was with the latest Win10 Iso download.

Checked WSUS and feature on demand is checked.

Easy fix is to bypass WSUS temporarily...
UseWUServer set to 0
Install Dot Net 3.5
Set the reg key back to 1
