问题描述

最诚挚的问候，

Need to know the Upgrade/Distribution path defined for Win32 Desktop Applications to UWP Store Applications for end users.

With reference to https://docs.microsoft.com/en-us/windows/uwp/porting/desktop-to-uwp-distribute

It mentions way to uninstall existing Win32 application on launch of UWP application.

In case, after installation of UWP Application if user do not select Launch application then he is left with 2 installed applications.

There are 2 shortcuts for same applications which may cause confusion with user.

Is there any way for removing application at the time of installation or upgrade the existing Win32 application at the time of installation of UWP application from Store.

Thanks and Regards,

Koustubh

Hi   KoustubhS,

Actually the installation of Appx is unattended and we cannot modify it by code. So  we cannot remove the win32 application at the time of installation of UWP application. And I don’t think it’s either user friendly or reasonable for you to think about doing this.

Currently, best practice to build the migration process is the following:

  1.The purpose of UWP technology is to let user select what they want. So if you put any of your code to installation process, then user cannot know what happens.

  2.Firstly, we need to make sure that your two apps are recognizable by this way: go to the appxmanifest file -> Application -> Display name -> change as 'xxx_App-UWP'. like this:

    Then, we put uninstall related code in windows_load method, this detection will happen whenever your app starts. And now it’s your choice to help your user to make their choice. If they want to keep both two apps, maybe you can disable this detection.

  3.When loading your app, you can also add the method "IsRunningAsUWP" to detect whether or not you are running as a packaged app or not. In this way, you can show different title to you customer. So they clearly know the difference here.

For details, check the following blog about IsRunningAsUWP https://blogs.msdn.microsoft.com/appconsult/2016/11/03/desktop-bridge-identify-the-applications-context/

I strongly recommend that you follow this process to build your app.
