Good day fellow simmers.I remember reading somewhere that in order to install the PMDG 737-800/900NG, you'd have to install the 600/700NG first?? I'm talking about the boxed version.Is this a misunderstanding on my part and I can go ahead, and buy the 800/900NG??It would cost me less$$Thanks in advance.Golli.

I can't speak to boxed -800/-900, but the download version requires the "base" package (-600/-700) be installed before installing the -800/-900.

I bought the boxed version (Aerosoft) and it worked perfect without the 6/700 pack which i don't have.CheersPeter

As Peter said, you don't need the 6/7 to install the 8/9 boxed pack. Works just fine.

I'll go ahead and buy it then.Thanks guys.Golli.
