Workaround for Windows Store Error 0x80073cfb

I am running an Insider Preview version of Windows 10 (1809 build 18305.1003 when I write this). Not sure if this has to do with the store error but this workaround should work on all builds should you encounter this error.


I wanted to download the “Daily Desktop Wallpaper” application from the Windows Store, or Microsoft Store as the program is called. The download starts and then stops, eventually timing out and resulting in a Windows Store Error 0x80073cfb. Restarting the download results in the same error message, over and over again.

I tried several workarounds and “fixes”, but none worked.
This next method worked for me.

Download and install Fiddler ( if you don’t have it installed yet.
When it’s installed click “WinConfig” (if this is the first time Fiddler runs, it will open with the WinConfig dialog), and select only Windows Store.
store_error_01This will tell Fiddler to only monitor web traffic from the Microsoft Store program and ignore anything else.
Click “Save Changes” and close the WinConfig dialog.

If Fiddler already captured some entries, remember which is the last one, or simply clear everything first, using CTRL+X (Edit -> Remove -> All Sessions).

Switch to the Windows Store program and retry your download. Immediately pause the download when it starts to download the first couple of KBs.
Leave the Store application open.

Switch to Fiddler and find the first HTTP 206 entry. It looks something like this:
Right click this entry and select Copy -> Just URL.

Close Fiddler, open a browser and paste the URL.
If you copied the correct URL a text-file download should start.
Save this somewhere where you can find it. I downloaded to C:\temp. The file will be a .txt file, but it really is an .appx file. There’s no need to rename it though.

Now open an administrative PowerShell prompt and navigate to the location where you saved the .txt file.

Type “Add-Appx” and press tab. Then type the first couple of letters for the .txt file name and press tab again. This should give you something like

Add-AppxPackage .\cc0f1e96-8dc5-46f8-b54a-9f51ebeb1f67.txt


Then press enter. This will install the AppX package and you can now find it in your Start Menu and run it.

Closing and opening the store will then also show that the application is now installed and can be launched.

The reason you need to keep the Store application open on the paused download is that you need a valid license file for the downloaded AppX package while you install it. The download in the Store application takes care of that.

    Hello Sir Arjan, hope Im not to late to contact you. I did install a pirated(cracked) version of Forza Horizon 4 game before and I did uninstall it(maybe not completely on the system). However now, I encounter this error 0x80073cfb during the installation of forza horizon 4. I did this method step by step and still I end up with the same issue which in the powershell it tells me this.

    Add-AppxPackage : Deployment failed with HRESULT: 0x80073CFB, The provided package is already installed, and reinstallation of the package was blocked. Check the AppXDeployment-Server event log for details.

    Hey Jeffery,
    Try this:
    (run powershell as admin)
    get-appxpackage -name Microsoft.SunriseBaseGame -AllUsers

    to get the PackageFullName and then

    remove-appxpackage -package PackageFullName -AllUsers

      I too hope i am not too late.

      My issue is that since FH4 is big and my internet isnt the best it will take me around a week to get it downloaded. I use IDM to download the file and after, lets say a day, it stops downloading and i need to grab the link from the windows store again. I dont have a problem with this, but the problem is that IDM tells me that it found they arent the same files and it need to be downloaded again from scratch. This is obviously not very pleasing. Progress worth of 3 days is lost. So i was wondering if you could give me some advice on this. Im now downloading it in Chrome, but then i fear if the download stopped and i needed to refresh the link, i wouldn’t be able to since that is not something Chrome allows you to do.

    Hello Arjan,

    I have purchased Forza Horizon 3 Blizzard mountain pack from windows store. This is a legit purchase. I have updated my OS as well. When i try to download through the store, i get the 0x80073CFB error and have resorted to powershell approach. the file i downloaded from Fiddler is an Eappxbundle format file and i have saved it in E:\Windowsapps. When i tried the powershell instructions mentioned above, i got the following error.

    “Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF0, Package could not be opened.
    error 0x80070199: Opening the package from location
    Microsoft.ForzaHorizon3BlizzardMountain_2016.1203.53.2_neutral_~_8wekyb3d8bbwe.EAppxBundle failed.
    NOTE: For additional information, look for [ActivityId] a5eca880-364d-0000-b2c1-efa54d36d601 in the Event Log or use
    the command line Get-AppPackageLog -ActivityID a5eca880-364d-0000-b2c1-efa54d36d601

    Please advise on how i might be able to overcome this problem.

    omg this method is brilliant. it worked for Forza Horizon 4. I had tried installing an illegitimate version earlier and now the legit file was getting an error while downloading. I followed your steps accurately and got successful results. A huge thanks to you, my friend!
