After reformatting my hard drive, I installed FS9 from scratch, with all my addons. I have the PMDG 600/700 installed. I have yet to install the 800/900 series and FS2crew. I remember reading somewhere about a proper installation sequence; first FS2Crew, then the 700/800, or is it the other way round?Or maybe it doesn't matter?Eytan Ornstein

Hello Eytan,Install order is this for the PMDG 737 version.1. Install the PMDG 737 with the 800/900 upgrade (I assume you have that, the 800/900 Upgrade).2. Install *all* updates for the PMDG 800/900 upgrade series from PMDG including the Optional Models Upgrade. That is very important.3. Install FS2Crew for the 800/900.4. Install all 3 upgrades for the 800/900 version of FS2Crew. It will also work with your 6/700 models, too, after you apply the updates.*Only install the updates if you bought FS2Crew via the FS2Crew website. Eytan, I checked, and this does apply to you.Cheers,Bryan
