Hey everyone,

I have been using whatsapp on windows from a long time now but yesterday I had a meeting on it and when I tried opening it from my task bar(windows 10), it didn't work and the same with any other method.

One thing I noticed is a semi filled white bar and when I went to the MS store, it showed that it needed an update and when I did try, it was almost complete and then it showed an error with the code: 0x80073cf9.

Please help me.

regards,

fellow window user

    I have the same problem and tried your solution, but, when I get to to the point of re-registering and reinstalling the Microsoft Store app, I get the following error message on Windows PowerShell (Admin):

    Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF9, Install failed. Please contact your software vendor.

    (Exception from HRESULT: 0x80073CF9)

    NOTE: For additional information, look for [ActivityId] 1c848a04-37eb-0000-189f-851ceb37db01 in the Event Log or use

    the command line Get-AppPackageLog -ActivityID 1c848a04-37eb-0000-189f-851ceb37db01

    At line:1 char:53

    + ... | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.I ...

    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

    *+ CategoryInfo          : WriteError: (C:\Program File...ppXManifest.xml:String) [Add-AppxPackage], IOException* 

*+ FullyQualifiedErrorId : DeploymentError,Microsoft.Windows.Appx.PackageManager.Commands.AddAppxPackageCommand*

    Could you please advise on how to proceed?

    Here is a workaround: https://github.com/microsoft/WindowsAppSDK/issues/4881#issuecomment-2480939942

    The problem is the Windows App SDK, used to create modern native Windows apps like Whatsapp on the Microsoft store. The team said it's working on a solution.

    I got the error on this step. I am not able to open WhatsApp app on windows. It was working fine earlier. I think that this problem started only after the new patch update few days back.

    ================================

    **Re-register and reinstall the Microsoft Store app
    Press Windows key + X
    Click and Run Windows PowerShell (Admin)
    Copy and paste the command below then press Enter.

    Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

    =====================================

    Error Message:

    =========

    PS C:\WINDOWS\system32> Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

    Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF9, Install failed. Please contact your software vendor.
