.Net Framework 3.5 fails to install with error code 0x800F081F

Original Title: Error installing .net framework 3.5 sp1

I did a refresh of my install of windows 8 pro (64 bit), because Weather and several other apps were failing (they started, then the main window closed, but the small window stayed in the task list to the left; event viewer gave access permissions errors).

This seemed to sort most of the apps BUT now I cannot re-install many programs as they need .net framework 3.5 and this fails to install with error 0x800F081F. I even tried downloading the full installer and running locally but it still gives the same error!

I need the framework to work with OpenXML development, a large part of my work.

(I should also point out the refresh says most apps are retained - it fails to mention all applications are removed!)

    Simple - I need the old frameworks, 3.5 and 2.0. If you install 4.5.1 (which I now have on Windows 8.1) it does not give you this.

    Why did you install an Old version instead of the New Latest version which is 4.5.1 from the link I gave above!?

    Since I started this thread I have tried all the solutions which are out on the internet with no luck.

    I then had to "wipe" my laptop and install a clean version of windows 8 pro. I then installed .net 3.5 before doing any updates and this worked.
