Sorry, but not possible. All the RealScenery installer does is unzip downloaded files and nothing more. Within those downloads is strictly the scenery, and as you can see in this forum, this is far from a redundant issue. Based on your assessment, it's quite clear that M54 is your issue, and you are likely missing a required library for it. Which one, I do not know. Facades are primarily used for objects or simple buildings, both of which are non-existent in the dsf "code" of RealScenery. It's quite literally impossible, and even further exemplified by the fact that removal of just that one scenery of all the others you have allow RealScenery to run just fine.
