.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!)

    Hi all,

    I'd like to agree with  "ColinZarzour".

     I have tried several solutions without having the problem solved. In all attempts I have the error code [0x800F081F] shows up with "Windows couldn't find required files to complete the requested changes. Make sure zou're connected to Internet, and try again". Amazingly! I'm connected to Internet during the installation.

    This is really strange!

    Unfortunately, I have some application programs require the .NET 3.5 to execute.

    D. F.

    Hi Imran,

    I have tried the command prompt solution, multiple reboots, the windows features solutions, and wiping the software and reinstalling it all, i still am left with the error code 0x800F081F.

    Do i need to put the source files in a specific folder and cite that in a command prompt code? if so where are these source files? I dont understand why nothing thats recommended works. I, like Mr. Marlow, need to use certain development tools that require NET 3.5

    This problem only began after I too refreshed my PC because of initial problems with the OS. the problems are solved (mostly, messaging still doesnt work at all).

    Any ideas? the above links were unhelpful as well as much time scouring forums.
