Addit down load

Hi All,

I am a new user, looking at available down loads I came across add it for SFX which seems a very useful bit of kit, my question is does it work with the steam version of FSX. This may seem a very basic question but I am that new to it, hope someone can help . Thanks

The majority of downloads work with Steam, some are marked so.
You will run across the occasional one that doesn't.
