Having issues getting the graphic overhaul mod to work in Morrowind in steam. All the patches seem to install successfully. Apart from the MGEgui.exe that doesn't seem to launch. I've ticked all the patches in the data files. When I play Morrowind. It says there are warnings: One or more plugins could not find the correct version or files depends on check the warnings txt file:

One of the files that "Better weaponz (rev1.2_DWEM).esp" is dependent on has changed since the last save.
This may result in errors. Saving again will clear this message
but not necessarily fix any errors.

There is a huge list of warnings with the esp files.

Any help would be appreciated. I am currently also running Windows 7 64bit.

Since you have steam, you'll have to read the bottom part of the installation guide.

Have you disable the Steam in-game community feature? If not, you can disable that by going to Steam's settings menu, then going to the in-game tab.

You must redate the three BSAs for the game back to their original dates. You can use any program, but here is one: http://www.softpedia.com/get/System/File-Management/Attribute-Changer.shtml
The original dates are:
01/05/2003 Bloodmoon.bsa
21/06/2002 Morrowind.bsa
29/10/2002 Tribunal.bsa
This will make texture replacers and other mods work correctly.

The warnings you mention are usually harmless, but you can easily get rid of them with Wrye Mash. (by updating the Masters for the esps, and updating your Save file afterwards)

I think he isn't talking about Morrowind Overhaul.
Better Weaponz is not included in my pack.
Anyway yeah, do what they said
