hi this is probably an annoying question but i have mods for mwe and mwse so what do i use to launch it? it's all to confusing please help thnx

MGE has MWSE built-in. Just run MW through the launcher and both will be on, so long as you set up MGE and enable the internal version of MWSE.

but what about mwe?

Sorry, I read that as MGE, not MWE. I don't know then.. I don't use either.

You launch MWE. The interface should have a button for launching Morrowind. As I recall (and it's been a while since I used MWE), you need to "point" it at the Morrowind executable, so it knows what program to run. Instead of doing that, point the button to your MWSE loader. That way, you can run MWE, and launch MWSE from it. Then MWSE will in turn run Morrowind.

Note, there have been some reports of conflicts between the two. I myself eventually (and reluctantly) gave it MWE, as a result. But if it works for you, go for it.

hehe confusing.... thanks iv'e set it up now

If you can avoid using MWE, however, that's definitely recommended. It has some nice features, but it's horribly buggy and is almost guaranteed to kill your saved game sooner or later.
