Here's a tutorial for getting your SimConnect to work. It's not the answer to everything with Steam but it should help out on a few things.
If you download Steam and do not change where it downloads programs to your hard drive the default is:
Program Files (x86)-
Steam-
steamapps-
common-
FSX-
SDK-
Core Utiltities Kit-
SimConnect SDK-
LegacyInterfaces-
Within that folder are the three folders that you run the SimConnect.msi program.
As far as the order goes, I'm not sure if there is one.
If you have any fixes to these or any other addons feel free to post below.
