If it is not implied that they mean sp2 or greater then you should not be installing thier product on FSX Exceleration either based on the jist of the EULA interpretation in these threads.

I have installed literally thousands of scenery files into FSX and never needed to modify any file within the scenery. Do sceneries installed into SE need modification beyond placing them into the correct directories?
Always remove the senery from FSX before moving it to a new location or you will get lots of errors as FSX fails to find the bgl at the old location.
SceneryConfigEditor v1.1.0 might let you rename the directories since it does not bring up FSX to do its job, just mods the cfg files.
