Microsoft Store app missing.

My MS store app is missing and for 3 days now I receive a message stating reinstalling Microsoft Store,  shows progress and then another message tells me the reinstall failed and will try again later?  What can I do to resolve this?  Thanks

What i did was the app reset. Now its nowhere . Not in Cortana, Apps and Features, etc. I ran the troubleshooter from Microsoft. both inbuilt and the one downloaded from MS. And I can get this message " you need a new app to open this ms-windows-store. "

 Is it completely gone? or can I reregister it ?

Yes, I just got this same problem. 

PS C:\WINDOWS\system32> Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Add-AppxPackage : Cannot find path 'C:\Program Files\WindowsApps\microsoft.windowsstore_11811.1001.18.0_x64__8wekyb3d8b

bwe\AppXManifest.xml' because it does not exist.

Any ideas how to get the store back? I just performed a complete windows restore and the store was gone after this...

If I try to run the troubleshooter it just says I need Windows Store app for this....

Press Windows key + X

Click Windows PowerShell (Admin)

At the command prompt, type the following then hit Enter:

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

Restart, then try launching the Store again.

I have tried this as well as every method listed on all the microsoft pages concerning this issue- including a reset- and nothing brings the store back.

Wrong Place..  u should be in the windows powershell, just go to search and write powershell, rightclick on powershell and run as administrator
