For example, I downloaded the most popular armor of tesnexus.com, the tyrael armor.
I installed it as adviced in the readme, copied all the files to the data folder and checked the tyrael armor.esp in the launcher's the data files
It was said in the readme that armor can be bought from a fighting chance of imperial city. So I went to buy it, and couldn't find the armor.
So I've been looking for the answer for quite a while now. I have vista, and I know it's tricky to install mods for vista. I also found some advice asking around internet.
I've tried a lot of things.
Installing oblivion to different place (C:\Games\Bethesda Softworks\Oblivion, C:\Bethesda Softworks\Oblivion...) running as administator, runninh using the xp sp2 compatability.. Nothing seems to work.
Anyone knows a solution? I'd like to hear it.
