The error message "This app package is not supported for installation by App Installer because it uses certain restricted capabilities" typically indicates that the application you are trying to install is attempting to use features or capabilities that are restricted by the App Installer. This can happen if the app package is designed to require permissions or capabilities that are not allowed for sideloading or installation through the App Installer.
To resolve this issue, you can consider the following steps:
- Check the App Capabilities: Review the app's manifest file to see which capabilities it is requesting. If it requires capabilities that are restricted, you may need to find an alternative method to install the application.
- Use PowerShell: If the app is not compatible with the App Installer, you might try installing it using PowerShell with the
Add-AppxPackagecommand, which may allow for more flexibility in handling app installations. - Developer Mode: Ensure that your device is enabled for Developer Mode or Sideloading apps, as this can sometimes help with installation issues.
- Consult Documentation: Refer to the official documentation for any specific requirements or limitations related to the app you are trying to install.
If these steps do not resolve the issue, you may need to consult the developer of the application for further assistance or look for a version of the application that is compatible with the App Installer.
