It perplexes me a little bit how the .msi file would get encrypted but none
of the other files are. As pointed on in a different for of the thread, I
could maybe see how the "Package Cache" might inherit encryption from
parent folders and propagate down to all the payloads... but I'm not seeing
how just the .msi file gets marked encrypted. That is still a mystery to
me. However, if you have consistent repro we should try a couple things in
burn and see if we can solve the root issue.
