So the question is how does a disc user update to SP1D?
Mind you Here I'm talking about a website called flight4fantasy who re-sells the PMDG Aircrafts. One of my friends bought it from their physical store. Thus he is in a state of confusion on how to upgrade to 1d and obtain the Operations Center as he is very fond of the Poseidon .
Hope there is a way . He has the original discs btw.
Thanks in advance!
