Uninstalling Calculator App Windows 10, Package could not be registered error

My Windows 10 calculator stopped working. I can't seem to re-install it using the PowerShell methods described on various Google searches. I receive 'Package could not be registered' errors.

Here's what I have been getting:

PS C:\Users\Paul> Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1601.49020.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode Add-AppxPackage : Deployment failed with HRESULT: 0x80073CF6, Package could not be registered.

Is there some way to remove the calculator app from the registry to I can re-load it through the Microsoft Store?
