Let’s look at the description of the process as it relates to each of the listed solutions.
1] Initial checklist
Before you proceed with the solutions below, you can complete each of the following tasks, and after each task see if you can be able to install the app using the Add-AppxPackage PowerShell cmdlet without issues.
- Install the app using alternative means. Assuming there’s no particular reason why you need to install an app available on the Microsoft Store using the Add-AppxPackage PowerShell cmdlet, you can as well get or deploy the app directly from Microsoft Store app on your Windows 11/10 device. Alternatively, you can use the Winget command-line utility to download/install apps on your device from Microsoft Store.
- Update Windows. In some cases, problems do occur due to a bug and the software vendors or developers will usually release updates for their software. These updates contain fixes for the bugs reported by the users. So, it’s recommended to always make sure Windows is updated to the latest build/version as and when due to get rid of already known bugs that might present on the OS. This also ensures you’re running the latest version of PowerShell. After installing the latest Windows update, check if the issue persists.
- Edit the AppxManifest file. You should do this after you have updated Windows to the latest build. Inside the referenced app folder, you need to edit the AppxManifest’s “TargetDeviceFamily” line as follows and make sure to replace the WinBuild placeholder with your current Windows build number. Afterward, run the Add-AppxPackage command.
<TargetDeviceFamily Name="Windows.Desktop" MinVersion="10.0.WinBuild" MaxVersionTested="10.0.WinBuild" />
- Run Windows Store Apps Troubleshooter. The inbuilt Troubleshooters are designed to help PC users automatically fix some common problems that they may encounter on their Windows devices. In this particular case, running the Windows Store Apps Troubleshooter would be helpful. It’s a good idea and we recommend running the troubleshooter for Microsoft Store apps-related issues.

2] Turn on Developer Mode to enable SideLoading of apps
As already indicated in the error message, the Add-AppxPackage Deployment failed with HRESULT 0x80073CFF due to the device the app in question is installed not being registered with a Windows developer license for side loading applications. In this case, to resolve the issue, you can turn on Developer Mode to enable SideLoading of apps on your Windows 11/10 device using the following steps.
- Open Windows Terminal as an Administrator.
- In the PowerShell console, type or copy and paste the following command and hit Enter:
- In the For developers page that opens in the Settings app, toggle the button to On for Developer Mode.
- Click Yes on the prompt.
- Exit Settings app.
You can now attempt to download the application again. But keep in mind that this action is not ideal to keep on or as a workaround, as it loosens restrictions on symlinks and a few other things. So, as a precautionary measure, you can turn off Developer Mode once you have the app installed on your device.

3] Create a new User Account
Every other thing being equal, in some cases problems like the issue you’re currently facing can occur in a specific user account especially if the account/profile is corrupted. In this case, you can create a new user account and then see if you can successfully install the app from that user account. If everything is working properly on the new account and there are other issues with the old account, you can transfer your files/data to the new user profile and then delete the old account/profile.

4] Configure Group Policy to allow all trusted apps to install
If you’re encountering this issue in an enterprise environment, you can configure GPMC on the local device to allow all trusted apps to install. To perform this task, follow these steps:

- Navigate to the following path:
Computer Configuration > Policies > Administrative Templates > Windows Components > App Package Deployment
- At the location, on the right pane, double-click the Allow all trusted apps to install policy to edit its properties.
- In the policy’s properties window that opens, select the radio button for Enabled.
- Click Apply > OK to save changes.
Note: Before the app package is a trusted app package, the (root) certificate, that is used for signing the app package, has to be trusted. So, to configure Group Policy to correctly import the root certificate for all computers, follow these steps:
- Open the Group Policy Management Console.
- Navigate to the following path:
Computer Configuration > Policies > Windows Settings > Security Settings > Public Key Policies
- At the location, on the right pane, right-click Trusted Root Certification Authorities.
- Select Import.
- In the Certificate Import Wizard that opens, do the following:
- On the Welcome page, click Next.
- On the File to Import page, Browse to the certificate and click Next.
- On the Certificate Store page, click Next.
- On the Completion page, click Finish.
