@Matt: You can delete it, but the launcher wont search for updates corretly anymore if you do so. Also language changing via the launcher won't work anymore. You also need to delete old Create a Heroes, you can simply restore the "My Rise of the Witchking files" folder via the launcher if you click on "Fix a non starting game", but be aware that it deletes the whole folder, so save your maps and replays before.
@Naz: It should not interfere, but I did not test it yet. You need to disable Edain for launching SEE for sure.
Nazgul and Turin Turumbar. I think you can play both at the same time. Because the Edain is installed in the ROTWK folder and SEE is in a different folder or in the future I don't know will add files in the folder of the BFME 2. I already played Edain mod and after finished the game I switched the Image and I could play SEE
