Absolutely, you can get general instructions for multiple installs in the pinned topic: "How to run Multiple Copies of Morrowind".
What I did was install Morrowind to c:\morrowind then install it again to c:\arktwend, and then install arktwend stuff into c:\arktwend. Arktwend needs the .bsa's from MW/TB/BM, but it doesn't need the .esms.

Good news! I feel silly for missing that thread :wacko: but I am definitely going to try that then. Thanks
