Hi,
I search MSIX supported-platforms like following thread, it support on following versions of Windows:
Windows 10, version 1709, and later.
Windows Server 2019 LTSC and later.
Windows Enterprise 2019 LTSC and later.
https://learn.microsoft.com/en-us/windows/msix/supported-platforms
But is not working on Windows Server 2019 LTSC ?
What I need to do ?
Is there an answer ?

This is unlikely to be directly related to MSIX or MAUI. From your previous thread about Server 2012R2 you had an error installing the WinUI components on that platform, which is expected since the earliest WinUI support is in 1809.
Can you please provide exact details of what you are doing and in what way it fails on 2019? If there is an error message, what is it?
Do you have the Server Desktop Experience installed?
Do you have the WinUI runtime installed on your 2019 server? What version? Do other WinUI apps run correctly?
Before I installed msix core the masix was not responsive.
After installed msix core i get error could not open the msix.
Server Desktop Experience => not installed can you give link to download if needed.
WinUI runtime installed on your 2019 server => not installed can you give link to download if needed.
Wait for your instructions.
Do you have an answer?

We cannot provide a good answer without knowing what the problem is. Unless you provide details, we're only guessing.
That said, the Desktop Experience is installed when you install the server. I don't believe it can be added after the fact. See https://learn.microsoft.com/en-us/windows-server/get-started/whats-new-in-windows-server-2019#desktop-experience
Desktop experience
Because Windows Server 2019 is a Long-Term Servicing Channel (LTSC) release, it includes the Desktop Experience. (Semi-Annual Channel (SAC) releases don't include the Desktop Experience by design; they are strictly Server Core and Nano Server container image releases.) As with Windows Server 2016, during setup of the operating system you can choose between Server Core installations or Server with Desktop Experience installations.
The Windows App SDK is generally installed by the store or your MDM when you install your application. If you want to install it separately then you can find the runtime package at https://learn.microsoft.com/en-us/windows/apps/windows-app-sdk/downloads . Installing it directly is probably not the right solution for a production system.
Depending on what your actual problem is these may or may not provide a full solution. If you need further help you will need to provide details about your problem.
n event view I got this error:
No applicable cross-architecture framework was found for package AutomationClient_1.1.10.0_x64_bwz0vybr94zxt. This package
depends on framework "Microsoft.WindowsAppRuntime.1.0" published by "CN=Microsoft Corporation, O=Microsoft Corporation,
L=Redmond, S=Washington, C=US" with minimum version 3.469.1654.0. The frameworks with name "Microsoft.WindowsAppRuntime.1.0"
currently installed are: {Microsoft.WindowsAppRuntime.1.0_3.469.1654.0_x64_8wekyb3d8bbwe}
What should I do?
This the exact details when i click on msix:
"You'll need new app to open this ms-appinstaller"
and here the control panel.
Wait to your answer what to do ?
The note regarding event viewer not relevant.
I tried to install both, but same problem:
his the exact details when i click on msix:
"You'll need new app to open this ms-appinstaller"
Can you please answer ?
I recommend you open an assisted support ticket for help on this. Your environment is still not clear and it's not clear what the problem is. I suspect you have a Server 2019 configuration issue and not a MAUI issue, and talking to somebody directly will help narrow down what exactly that is.
You will need to have the Desktop Experience installed as well as any dependencies for your app (.Net Framework, Windows App SDK, etc.) that aren't included by default in Server 2019. See https://learn.microsoft.com/en-us/windows/msix/msix-server-2019
Can you please give me exact links for Desktop Experience as well as any dependencies for my app and I will installed it ?
Desktop experience is chosen when you install the server (I suspect you have done this). I don't have enough context to provide any answers beyond what I've already posted in this thread.
If you need more help with this, please open a case so that somebody can work with you to understand your specific scenario.
