Correct installation order magnetic variation

[gura75 0]

Any suggestions on correct installation order taking into account magnetic variation. Having installed FSX from scratch, should one install payware scenery/airports and pmdg + service packs before installing/updating magnetic variation updates? gura75

I dot know that it actually matters, but I would probably do the magvar last.Edit: if I recall correctly, fsx has two sets of magnetic variations. This update only corrects in that area, while each individual airport has its own local magvar settings in addition to that. If that's the case it wouldn't matter when you install it.
