.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!)

    Thank you!  This worked perfectly on my SP2 as well.  The .NET 35. feature was indeed checked afterwards.

    Hi, unfortunatly I am struck by the same issue. Tried every possible solution without success...

    I do not want to do a fresh install as I did it just three ago and it is a pain in the ***. Does anyone have an update about this ? Would be great ...

    Otherwise, if I do a restor to the first day of my refresh, would it work ?

    Second solution, if I uninstall all the Windows Updates, could it work ?

    Thanks ...

    This behavior can also be caused by a system administrator who configures the computer to use Windows Server Update Services (WSUS) instead of the Microsoft Windows Update server for servicing. In this case, contact your system administrator and request that they enable the Specify settings for optional component installation and component repair Group Policy setting and configure the Alternate source file path value or select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) option.

    To configure the Group Policy setting, follow these steps:

    Start the Local Group Policy Editor or Group Policy Management Console

    Windows 8 and Windows Server 2012: Point to the upper-right corner of the screen, click Search, type group policy, clickSettings, and then click Edit group policy.

    Windows 8.1 and Windows Server 2012 R2: Point to the upper-right corner of the screen, click Search, type group policy, and then click Edit group policy.

    Expand Computer Configuration, expand Administrative Templates, and then select System. The screen shot for this step is listed below.

    Open the Specify settings for optional component installation and component repair Group Policy setting, and then select Enabled. The screen shot for this step is listed below.

    If you want to specify an alternative source file, in the Alternate source file path box, specify a fully qualified path of a shared folder that contains the contents of the \sources\sxs folder from the installation media.

    Example of a shared folder path: \server_name\share\Win8sxs

    Or, specify a WIM file. To specify a WIM file as an alternative source file location, add the prefix WIM: to the path, and then add the index of the image that you want to use in the WIM file as a suffix.

    Example of a WMI file path: WIM:\server_name\share\install.wim:3NoteIn this example, 3 represents the index of the image in which the feature files are found.

    If it is applicable to do this, select the****Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) check box.

    Tap or click OK.

    At an elevated command prompt, type the following command, and then press Enter to apply the policy immediately:

    gpupdate /force
