Sounds like the script to a REALLY bad movie.

Why can RDNA, Rendo and everybody else (including independent vendors) create zip files that work as expected? Like content zip files have always worked since I've been playing at this hobby (7+ years now). I have no problem installing zips from them.

I think Stan is right and DAZ is trying to make installing content so complicated and confusing that no newbie would dare buy content from another store because they feel like they wouldn't be able to install it. Bad DAZ.
