You’ll need a new app to open this ms-windows-store – Windows Store problem

Windows Store, despite being a very refined application, can be bothersome. One bug that users may face at times is that when they try to open the Windows Store, it does not open, but instead, throws up an error message: You’ll need a new app to open this ms-windows-store on your Windows 10. If you face this problem, this post will help you fix the problem.


You’ll need a new app to open this ms-windows-store

The interesting part about the error is that you can’t update or download any app, unless you open Windows Store. This error might appear if some Windows Store application files are orrupted or missing.

Before you begin, make sure that you have installed the lates Windows Updates and are signed in with your Microsoft Account. Also create a System Restore Point first. Now to fix this issue, proceed with the troubleshooting as follows:

1] Re-register the Windows Store apps

Type ‘powershell’ in Start Search and right-click on the Windows Powershell which appears in the results, and select Run as administrator.

Now enter the following script in the Powershell window and hit Enter:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Let the script run and then restart the system.

2] Reset Windows Store cache

Sometimes, the Windows Store cache could create issues and we might need to reset it. To do this, press Win+X and click on Command Prompt (Admin)

Run the command WSReset.exe in an elevated command prompt window and restart the system.

Check if it resolves the issue.

3] Run Windows Store App Troubleshooter

The Windows Store Apps Troubleshooter for Windows 10 will scan your computer, identify the problems and attempt to fix the issues automatically.

4] Reinstall the Windows Store

In an elevated PowerShell windows, type the following and hit Enter:

PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"

Or you may use our freeware 10AppsManager to uninstall and reinstall the Windows Store and see if that works for you.

5] Reset Windows Store via Settings

Open Settings > Apps > Apps & features. Under Apps & features, using the Search this list bar, search for Windows Store. Now click on the Advanced options link to open the following panel.

Click on Reset to reset the Windows Store.
