  1. Windows Update (Error: 0x80071a91)


    I've recently had three different agents (at different times) try to help fix this problem but none of the methods they used worked.

    I need the update for .NET Framework so I can play a game. It continuously disables it and whenever I reenable it, it says I need to update.

    The following errors I've gotten after attempting different methods from various forums, posts, and videos are:


    Windows Update Errors:

    • 2019-01 Cumulative Update for .NET Framework 3.5 and 4.7.2 for Windows 10 Version 1809 for x64 (KB4480056) - Error 0x80071a91
    • 2019-01 Security Update for Adobe Flash Player for Windows 10 Version 1809 for x64-based Systems (KB4480979) - Error 0x80071a91
    • Update for Adobe Flash Player for Windows 10 Version 1809 for x64-based Systems (KB4462930) - Error 0x80071a91

    * Failed meaning it didn't work

    Removing and reinstalling .NET Framework, failed.

    Disabling anti-virus and windows defender in general, failed.

    Enabling .NET Framework 3.5 through Programs and Features, failed.

    Restarting my computer in safe mode, failed.

    Downloading these updates manually through the catalog, failed.

    Going through the DISM method clean-up, failed.

    Manually resetting the Windows Updates Components, failed.

    Renamed SoftwareDistribution and Catroot, failed.

    Downloaded an image (The agent tried this but it didn't work), failed.

    Resetted file system resource manager in CMD, failed.

    Disabled/Removed non-essential devices from the computer (Updates still didn't budge), failed.

    Made sure I had enough space (I have plenty, not a problem. Although, it's not a technical fail... It didn't do anything to solve the problem), failed.

    Troubleshooted the updates (Didn't detect anything, is it faulty?), failed.

    Reinstalled Windows altogether, failed.

    Tried Windows Media Creation Tool to perform an in-place upgrade, failed.


    If you can recommend some more things to try, it would be greatly appreciated. It's kind of saddening to experience this problem because of 2019's update but hopefully, it can be solved.

    :)
