.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!)
