MSIX installation doesn't even work in Windows containers (well, server containers, since client containers aren't available outside of the Sandbox). The error is literally "error text missing". It's so frustrating, because we really need an installer that can compartmentalize everything, but every time Microsoft tries to do it they either kill the project (Win32 containers on Windows 10X) or make it not work right for 90% of stuff (MSIX). There is tons of Microsoft software that cannot even be packaged via MSIX (Office, Visual Studio), I have no idea how they thought third party devs would be able to do it.
