2. Next, press the Yes button when prompted to run the app installer with admin privileges.

Configure Windows App Installation Settings

Suppose you are facing the unable to install app error while installing a third-party software outside the Microsoft Store. In that case, you should review and configure the Windows app installation settings.

Check App and System Architecture Compatibility

To ensure the successful installation of an app/software to your Windows system, you must check its architecture compatibility with your system.

2. Next, look for the System type under the device specifications section to know the architecture of your installed Windows OS.

4. Now that you have details about your system architecture, you can download the compatible setup of the app/software to run and install it.

Set Specific Windows OS Compatibility

Some apps and software are designed to run on a specific Windows OS hence making its installation difficult. To resolve this issue, you can assign specific Windows OS compatibility to install and run it on Windows 11.
