Some users reported that whenever they try to install programs on their Windows 10 PC, they’re seeing a dialog with a message that reads “The app you’re trying to install isn’t a Microsoft-verified app“. As a result, they’re unable to install apps and programs of their choice.
Users are seeing this message due to security features enabled in Windows 10, which only allow users to install trusted applications from Microsoft Store. It’s because the third-party software or program that you download outside of the Microsoft Store could be home to bugs or malware. As a result, affect your device after installation.
Usually, this error message appears when users running Windows 10 in S mode trying to install apps outside of the Microsoft Store. Unfortunately, there’s no way to fix this because Windows 10 S mode is designed for performance and security, and allows the installation of apps from the Microsoft Store.
In case, you want to overcome this limitation, then you need to switch out of S mode in Windows 10.
Fix – The app you’re trying to install isn’t a Microsoft-verified app
Although, if you’re already using Windows 10 Home, Pro, and other editions, then here’s how you can fix that:
Press WIN + I keys to open the Settings app and then head over to Apps > Apps & features.
Here on the right side, under Choose where to get apps section using “Installing apps from Microsoft Store helps protect your device” drop-down select Anywhere.
In case the, Choose where to get apps option is missing, then you need to make sure that you’re login into Windows 10 with Microsoft account with admin rights. If you don’t have admin access, then ask the administrator to grant access.
Choose where to get apps missing or greyed out
Apart from that, if the “Choose where to get apps” option is greyed out in Windows 10, then here’s how you can fix that:
In Windows 10 Pro edition, search Group Policy Editor and open the app.
Next, head over to Computer Configuration > Administrative Templates > Windows Components > Windows Defender SmartScreen > Explorer.
Here, double-click on Configure App Install Control. If it’s enabled, then set it to Not Configured. If it’s already set to Not Configured, then using the options drop-down select Turn off app recommendations.
After that, click OK and Exit.
In Windows 10 Home Edition, search Registry editor and open the app.
Next head over to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\SmartScreen
Here, on the right side look for two values ConfigureAppInstallControl and
ConfigureAppInstallControlEnabled, right-click, and select Delete.
After that, close the registry editor and reboot your device.
