Installation through manifest (.appinstaller file) fails with code 0x80072F76
Dear community, We are rather new to the entire AppInstaller realm and have run into a situation we simply cannot get our heads around. We have an application we have packaged as an .msix and wo...

In case you are not aware, Microsoft disabled using an external appinstaller xml file due to security concerns. They added the capability for it to be inside the package instead, and later also created a group policy that you can use to re-enable the external file capability. What was disabled is technically the protocol handler used. See this for how to enable:

Thank you Timothy for your swift reply. I was not aware of this (and will certainly look into the matter and see if it relates). It does not seem to be the problem, but you never know. 🙂
On that same note - when and if Microsoft decides to do such (rather fundamental) changes - how does one retain this knowledge/insight in a structured way? I’m an applications developer first and foremost and does not have a lot of experience with application packing and application deployment techniques. I usually use whatever is “current” and usually this has worked out fine (for the past 20 years).
Now – however – it’s gotten extensively complicated (mainly for efforts in making the process more secure, I presume/understand) but still – one needs to do this and one needs to understand the underlying concepts and “visions” of Microsoft. Is there a place (wiki, blog, release notes, anything) where changes, new features, guidelines etc. are publicly available – in relation to (Desktop) AppInstaller? So one can catch news such as the one you are informing me about now?
And more importantly – when you run into some trouble like this with “code 0x80072F76 – Unknown error” situations and absolutely no logging (anywhere I’ve been able to find) – where is the support or – even better – the documentation?
Perhaps you (who seems well versed in this area) or anyone else in the community knows or can share useful resources for beginners like myself?
