Hi, guys.I've just installed the PMDG 737-800/900 (I have the box version, bought in 2005). After starting FS (version 9.1), I select this aircraft, then start flight. All the screens in the panel appear black and almost all the switches don't work. The engines are running. Everything was file on my old PC, which run XP 32 sp2.I've used search, but unfortunately didn't find any solution.I would be really grateful if you help me.

Black display units usually means there is a validation problem, but I am not familiar with boxed versions and how they validate the copy as authorized. Your title mentions Vista64, maybe the problem is administrator rights have to be assigned to installer and all pmdg folders. I am using the 737 on Vista64 with no problem.Please sign your real name to posts in this forum.Thanks,
