A tutorial on how to because I have Vista as well. 1.Get WinRAR. 2.Download your mod. 3.Extract mod from WinRAR to ***(I made a folder for my mods in Documents). 4.Go into the folder where you extracted to. 5. All mods are different, so if it is things like armor or weapons, or quests, etc. Anything that has Textures, Meshes, and an ESP file, copy and paste into Oblivion Data folder (OS:C,Progam Files,Bethesda Softworks, Oblivion, Data). 6. If step 5 didn't work, read the ReadMe file in your mod and look for the *Installation* section. 7. If step 5 DID work, launch Oblivion WITHOUT OBSE and click Data Files, then check off the mod because it should be there. I hope this helps your Oblivion gaming. Mods are the main source of entertainment for PC Oblivion. Enjoy ;)
