Minecraft wont load

Hey, iv'e had tons of problems trying to get minecraft to work. It started of with me not being able to download it, the download always stopped at 90% then an error occured. After tons on research into how to fix this problem and days of talking to minecraft support I finally found a solution. I put what I think is this code into powershell:

PowerShell -ExecutionPolicy Unrestricted –Command “& {$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + ‘AppxManifest.xml’ ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}”

Or this code:

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

 

Then it finally downloaded properly, both from the windows store, the xbox app and the actual minecraft launcher itself. However now I can't open the game. When I click run I can sometimes see the red startup screen that says mojang, then it just closes itself. I don't know what else to do now, hope all this info is enough.
