The problem with saying the Installer licence comes after the download licence is that R'osity don't give refunds, except case-by-case, so there's no real choice by the time you've paid and downloaded. Usually if you refuse to agree at the licence screen you 're told to return the package for a refund. The best solution seems to be offering a more liberal replacement licence and allowing the user to choose which to accept, or to say in big letters in the Readme that you guarantee you are not going to enforce certain rights granted to you (the creator) by the licence.
