Requried App Runtime 1.5 Not availbale anymore

[Thane5]

Microsoft no longer offers Windows App Runtime 1.5 for download. Only versions beyond 1.6 are available. Therefore i can not run the demo projects.

[sotanakamura]

You can download Windows App SDK 1.5 in the following page.
https://learn.microsoft.com/en-us/windows/apps/windows-app-sdk/downloads-archive

I think 1.6 is compatible with 1.5. So you can use 1.6 instead of 1.5.

[Thane5]

i tried both 1.6 and 1.5 (1.5.0 and 1.5.7) None of them worked and the error popup came up everytime.

[sotanakamura]

It works in my environment. Did you install Python from https://www.python.org/?

[Thane5]

Yes. Initially i ran everything form a virtual environment in PyCharm, but now i also tested it with my system wide python installation and launched it via the console. Still, same error.

[sotanakamura]

Please run the following command and send the output

where python

and ensure that the runtime is installed by running the following command

powershell Get-AppxPackage -Name "*WindowsAppRuntime*"

[Thane5]

where python returned nothing

here are the app runtimes the other command found:

[sotanakamura]

Please use command prompt

[Thane5]

Ah sorry, here is what CMD found:

C:\Users\myname\AppData\Local\Programs\Python\Python312\python.exe
C:\Users\myname\AppData\Local\Microsoft\WindowsApps\python.exe

[sotanakamura]

Please run the following command in the cloned repo

python winui-xaml.py

[Thane5]

that makes the error popup appear,

After reinstalling Windows app runtime, I have had the same problem. I will explore it a little bit.

[sotanakamura]

The same issue is reported.
microsoft/WindowsAppSDK#4268

[sotanakamura]

It works on Windows 22H2.

Edition Windows 11 Enterprise
Version 22H2
OS build 22621.4391

[sotanakamura]

@Thane5 Do you still have this problem? When I installed the runtime v1.6.5, I didn't have the problem. Please try to install the runtime v1.6.5 and let me know the result. If you sill have this problem, please share the version of Windows.

Is there anyway to build with the dependency like msbuild property <WindowsAppSDKSelfContained>

[sotanakamura]

@luojunyuan You can get DLLs by downloading the redistributable msix package, renameing it to a zip file, and extract it. I think you need to put the DLLs in the proper directory, not in the directory where your script is stored.
