In this article, we will take a look at how MSIX technology handles log files whenever an installation issue occurs.

MSIX has been available for almost four years now, since Microsoft first announced it. Although 2021 did not deliver all of the advances I had hoped for, I was pleased to see MSIX adoption continue to expand on a regular basis.

When Win32 applications run inside an MSIX container, they behave differently than when they are installed natively. Because of that, we come across errors in the operations we often perform.

With Intune, Microsoft made it easier to deploy MSIX/APPX packages in your infrastructure.

Based on my experience, when working with beginner IT Pros who are starting out with MSIX, there's a common misconception when defining registry keys.

In 2018, MSIX was announced by Microsoft as the new universal package format for Windows 10 apps with the later support on desktop, mobile, and other Windows 10 devices.

Python is one of the most widely used programming languages, due to its versatility. In a previous article, we covered how to create an MSI for a Python application, where we first converted the Python into an exe and then created an MSI for that Python executable.

Sometimes, we have a package folder in our MSIX, containing files that are not part of the redirected locations list. Since all the folders need to be part of the known-VFS list, we need to use a fixup to copy those files from the WindowsApps folder (after the MSIX is installed) to the location you want.

Advanced Installer was the first application to fully support MSIX technology – and we truly believe in its power.

MSIX uses the same PowerShell cmdlets available for AppX packages. But Microsoft added aliases for them not to create confusion between the AppX and MSIX packages.Let’s go through some of them with a few examples.

Why does my MSIX app fail to find files from the package? The short answer is that this is related to how the files inside the VFS folder are, or are not, virtualized.

There's a certain feeling of relief and achievement when we finally launch our application to the Microsoft Store.

Sometimes we need to have a single distribution package as an MSIX, which includes MSIX supported features along with MSI features that are no longer available (such as old drivers).

MSIX delivered Shared Package Containers to allow applications to share their files and registries, enabling classic Win32 apps to communicate with each other without changing any code.

While for MSIs, this was an optional step, signing your MSIX package is mandatory. Microsoft’s MSIX technology requires the use of code signing certificates to deploy packages.

If there's something we've mentioned over and over again about MSIX is that it requires digital signing. We have a diversity of resources regarding this topic, from why it is a good practice to include a timestamp when signing a package, to automating the whole digital signing process of MSIX Packages.

Announced in 2018, MSIX was presented by Microsoft as the universal package format. Although it may not be widely known, the MSIX technology retains the functionalities for translations and localizations of Universal Windows Platform or UWP Apps.

Many of us are aware of the importance of securing our applications and how digital signatures are a solid way to avoid security breaches. For those looking into MSIX, you must know that Microsoft enforces digital signature for all packages within this technology. There is no exception.

A while ago we released a free tool for APP-V called TweakAPPV at Advanced Installer. Our purpose with this tool was to take App-V 5.x editing from the command-line to a new level by offering full access to the package contents.
