It’s crucial to ensure that the Package zip file is unblocked before extracting it. If it’s blocked, the AXUpdateInstaller won’t be able to access the files even after they are extracted.

To verify this, one can right-click on any file in the extracted package folder, go to Properties, and look for the Unblock checkbox. If it’s unchecked, it means the file is still blocked.

This is a valuable tip for anyone working with zip files and encountering issues with the AXUpdateInstaller.

Just before extracting the zip file, right-click on it > Properties and tick Unblock. and try again.
