Firstly, Morrowind may crash on startup with the error "Failed to load model: Meshes\BM_Snow01.nif". Installing Morrowind on Windows Vista/7/8 Editīecause Morrowind was developed for Windows XP, there are a couple of issues that arise due to the increased security when installing to the default C:\Program Files directory. Note: Morrowind Code Patch and 4GB Patch do not work with the GameStop/Impulse version of the game, so the Steam version is recommended instead. This is especially true for Windows Vista/7/8 users. The installation of Morrowind will appear to be a strange place to begin a guide on modding, but getting the installation right will avoid some issues that might appear in the future.
