Here are some reasons why you might be unable to find or install an app from the Windows Store:
The app isn’t available in your country or region. Although an app might be available in several different countries or regions, the publisher might have decided not to release it in your country or region. This means you can see the app description page on the web, but when you try to view the app in the Store, you’ll see a message that the app isn’t available.
Your preferences might be hiding apps. You can set preferences in the Store so it’s easier to find apps that use your preferred language or apps that include accessibility features. When these settings are turned on, apps that don’t meet your preferences are hidden when you browse or search the Store. For more info about preferences, see Set your preferences for the Windows Store.
Family Safety settings might be hiding apps because of age rating. Parents can use Family Safety settings to make sure that their child can’t view or install apps that are inappropriate for their age from the Store. For more info about Family Safety, see Use Family Safety with the Windows Store.
The payment method associated with your account isn’t from the country or region you’re in. To buy an app from the Store in a specific country or region, your payment method needs to be from that country or region. For more info, see Use the Windows Store in a different country or region.
The app is no longer available in the Store. In some cases, an app might have been removed from the Store. This means you can see the app description page on the web, but when you try to view the app in the Store, you’ll see a message that the app isn’t available.
Your PC’s processor is incompatible with the app. The Store automatically hides apps that are incompatible with your PC’s processor so you don’t install apps that won’t run on your PC. This means you might see an app that's available in the Store on one PC, but the same app isn’t available in the Store on another PC that uses a different processor.
Your PC doesn't meet the system requirements for the app. You won't be able to install an app if your PC doesn't meet the system requirements for it. To view the system requirements for an app, scroll to the Details section of an app's description page in the Store. If your PC meets the system requirements for an app, but you're unable to install it, check to make sure you're not signed in to the PC or the Store using a temporary or guest account.
Your PC was recently updated, but wasn't restarted. If updates for Windows were recently installed, you'll need to restart your PC before you can install apps from the Store.
If you've check all of the possible reasons listed and are still unable to find or install apps, you can try clearing the cache for the Windows Store on your PC.
Swipe in from the right edge of the screen, and then tap Search.(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then click Search.)
Enter run in the search box, and then tap or click Run.
Enter wsreset.exe in the Run command and then tap or click OK.
The Windows Store will open after the cache has been cleared.
