In most cases we think at this stage that many of our add-ons will work in the Steam Edition, but we are only able to provide technical support for add-ons which have been sold specifically as being compatible with FSX Steam Edition.

To the best of our knowledge, if you did not have the original boxed version of FSX currently installed at the time you installed FSX Steam Edition then all of our add-ons should work (assuming you have the up to date version of FSUIPC installed for FSX:SE, see below for details) without any problems. If you did have the original boxed version of FSX installed then certain add-ons that need to write information to files such as FSX.cfg, DLL.cfg and Scenery.cfg (common examples are scenery titles, AI traffic titles, amongst others) then these will not work without manual intervention.
