      [Fix] 0x800F0906 and 0x800F081F Error Messages While Installing .NET Framework 3.5 in Windows 8\/8.1<\/p>\n

      You might be aware of the fact that\u00a0Windows 8<\/strong>\u00a0and\u00a0Windows 8.1<\/strong>\u00a0operating systems don\u2019t come with\u00a0Microsoft .NET Framework 3.5\u00a0installed. But there are many 3rd party software programs which require .NET Framework 3.5 in your system. In such cases you need to install the .NET Framework 3.5 version in Windows 8\/8.1 manually.<\/p>\n

      There are 2 ways to install .NET Framework 3.5 in Windows 8\/8.1:<\/p>\n

        \n
      • Online Install<\/li>\n
      • Offline Install<\/li>\n<\/ul>\n

        In\u00a0Online Install<\/strong>\u00a0method, you install .NET Framework 3.5 using\u00a0Control Panel -> Programs and Features -> Turn Windows features on or off<\/strong>\u00a0option. In this method, Windows first downloads the setup files of .NET Framework 3.5 from Internet and then installs it in your computer system.<\/p>\n

        In\u00a0Offline Install<\/strong>\u00a0method, you use a built-in command to install .NET Framework 3.5 directly usingWindows\u00a0setup\u00a0disc without requiring Internet connection. You can also use\u00a0Microsoft .NET Framework 3.5 Offline Installer<\/strong>\u00a0to automatically install .NET Framework 3.5 offline in Windows 8\/8.1.<\/p>\n

        PROBLEM DESCRIPTION:<\/strong><\/p>\n

        Recently we have received many comments and emails from our readers regarding a few error messages while installing .NET Framework 3.5 in Windows 8\/8.1. Whenever users try to install .NET Framework 3.5 in Windows 8\/8.1, they receive\u00a0following\u00a0error\u00a0messages:<\/p>\n

        Error: 0x800F081F<\/strong>
        \nThe source files could not be found.<\/p>\n

        OR<\/p>\n

        Error: 0x800F0906<\/strong>
        \nThe source files could not be downloaded.
        \nOR<\/em>
        \nWindows couldn\u2019t connect to the Internet to download necessary files. Make sure that you\u2019re connected to the Internet and click \u201cRetry\u201d to try again.<\/p>\n

        It doesn\u2019t matter whether they try online method or offline method, the same\u00a0error\u00a0messages\u00a0and codes are shown by Windows.<\/p>\n

        PROBLEM REASON:<\/strong><\/p>\n

        Actually these error messages are coming due to following 3 updates recently released by Microsoft for .NET Framework 3.5:<\/p>\n

        • KB2966827<\/strong><\/li>\n
        • KB2966828<\/strong><\/li>\n<\/ul>\n

          Above mentioned updates are security updates for .NET Framework 3.5 in Windows 8.1 and Windows Server 2012 R2. These updates are applied via\u00a0Windows\u00a0Update\u00a0regardless of whether you have .NET Framework 3.5 enabled or not. If these updates are installed in your system and you try to install .NET Framework 3.5, you\u2019ll receive 0x800F0906 and 0x800F081F error messages.<\/p>\n

          PROBLEM SOLUTION:<\/strong><\/p>\n

          To fix this problem, you just need to uninstall these security updates from your system and then install .NET Framework 3.5. After successfully installing Framework version, you can reinstall the security updates without any problem.<\/p>\n

          So if you are also facing this problem, just follow these simple steps to fix the issue:<\/p>\n
