steam/steamapps/common/skyrim/data is the correct path so if that is where it's placed then you've installed it at the correct location.
If you get crash to windows check the readme and see if there is any info in which load order the file should be placed. You can also try crosschecking with other mods to see if you have any incompatible mods, rearrange you load order can also work. You do this by accessing the data files from the launchwindow.
You are sure there is only an ESP file and not any texture or mesh maps or something too?
