Am I doing it wrong?

Having problems installing the SDX, I have FSXdeluxe/Accel, installed the SDK that comes with deluxe and then then Accel's SDK ( it told me to do this) and then went to the dll.xml and changed the trues to false, but still nothing.
Does the SDK require an addon free install of FSX in order to work or am I missing something painfully obvious? Thanx for all replies!
