Inconsistent behaviour of windows App SDK runtime Installer

Question

Hi,

I'm working on WinUI3 desktop application in C++. We are building a Framework dependent unpackaged desktop application with this we were able to generate a single EXE application. But here to run this WinUI3 application we need to install Windows App SDK Runtime in target machine.

We are using Windows App SDK Runtime version 1.3.3, but when I install the installer from the website (Installer (x64) ) and run my WinUI3 application its giving an error saying

Later I figured out that it was not installing all the components. When I ran

" (get-appxpackage microwinappruntime*).packagefullname"

it was showing WinAppRuntime, Main and Singleton. But not DDLM. Later I had to install DDLM separately from website (Redistributable ). After that I was able to run my winui3 application.

Why is this inconsistent behaviour? previously it was installing all the 4 components but now only 3 and I have seen it only for version 1.3

Answer 1

Hi,

Welcome to Microsoft Q&A!

When I try to install Windows App SDK 1.5, it installs all 4 components. I suggest you could try to install Windows App SDK 1.5 instead of Windows App SDK 1.3.

When I install Windows App SDK 1.3.3, it seems like it only installs 3 components. It seems an issue, I suggest you could try to post the issue to WindowsAppSDK Issue for better help.

Thank you.

Jeanine
