If you're unable to run MGE 3.8.2 (After pressing the exe you get a notice that it has stopped working), then you have to do these steps. 1.: Make sure that Morrowind.exe, Morrowind Launcher.exe and MGEgui.exe have a check on the “Run this program as an administrator” (You can find it at right click -> properties -> compability) 2.: Launch Morrowind Launcher.exe (as administrator), press options and change the resolution to 800×600, press ok and leave launcher. 3.: MGEgui.exe should work now properly and not giving you an error anymore. I was having the same issue as yourself until I tried this, hopefully it helps you also.
