UWP app -Invalid package family name, after update certificate

sideload uwp app without certificate
deploy uwp app without store
uwp certificate
uwp remove certificate
uwp package installer
uwp sideloading
uwp app installer

I created app for uwp (win 10 desktop). I could not build package for store. I received an error: it is necessary to update the certificate. I have updated certificate and build my package. But when I upload the package to the store, I get the error:

Invalid package family name: MyPackage.xxxx_xxxx (expected: MyPackage.yyyy_yyyyy)
Invalid package publisher name: CN=XYX (expected: CN=xxx-xxxx-xxx-xxxx)

But I opened my app manifest and I see:

Published: CN=xxx-xxxx-xxx-xxxx
Package Family Name: MyPackage.yyyy_yyyyy

It is what expected. In "open sertificate" I see : Publisher -XYX.

How do I fix it all? Any ideas?

I solved this issue. I made a mistake when creating new certificate. It must be so:

  1. Open Package.appxmanifest.
  2. Go to the "Packaging" tab.
  3. Copy Publisher DN(number after CN=)
  4. Click the button "Choose Certificate" and select the item "Create test certificate..."
  5. Copy the publisher DN from step 3 to the first editable text field

Package a desktop or UWP app in Visual Studio, Use the Visual Studio packaging wizard to create an app package. If it wasn't, you will need to install the signing certificate to the Trusted Select Microsoft Store using a new app name in the first dialog and then click Next. I created an UWP app in our Microsoft Private Company Store, but with a wrong certificate. Now I would like to upload a new Package to this app with the correct Certificate. I created a new appxupload with a link to the correct certificate in the appxmanifest. But when I try to upload this the dev store gives me 2 errors: Invalid package family

I found this MSDN blog: https://blogs.msdn.microsoft.com/jamiedalton/2017/01/13/windows-store-error-updating-package-invalid-package-family-name/

The blog states that you should associate your App to the Store App using Visual Studio.

This seems to be the right answer.

Provision PCs with apps (Windows 10), Add apps to a Windows 10 provisioning package. In Windows 10, version 1703 , you can install multiple Universal Windows Platform (UWP) apps and Windows This is optional if you have a certificate for the app. Package family name: Specify the package family name if you don't specify a license. Use Visual studio to associate your app with the Microsoft Store:In Solution Explorer, right-click your project and then select Store > Associate App with the Store > Next >(sign in to the Microsoft Store) > select the App Name you have reserved>Next > Associate.

Update for Visual Studio 2019
  1. Open Package.appxmanifest from Solution Explorer
  2. Go to "Packaging" tab
  3. Copy Publisher name after CN=. Looks like a GUID
  4. Click "Choose Certificate..."
  5. Click "Configure Certificate..."
  6. Click "Create..."
  7. Paste GUID from #3 into "Publisher Common Name"
  8. Proceed to create and save certificate

Problem seems that it defaults to developer name instead of using the original GUID
