This is confusing me. Are you sure that you are not confusing the path where Oblivion lies with the path where Nehrim is going to be installed into?
Also, you don't just have to enable the Nehrim ESM/ESP; you also have to disable Oblivion's ones.

This deserves a new post! I seem to have fixed it! In fact, it seems to have been working all along!

I had thought, each time I started the game, that it wasn't working because it was using Oblivion's default start screen. BUT I just clicked new game, and it took me into Nehrim! So apparently either my start screen doesn't work, or the last update they did removed the starting screen, or something. I don't care. As long as I can play the game.

If I have any more problems, I'll post in this thread. Thank you for sticking with me and helping arvisrend, I really appreciate it!

More problems.

As soon as I entered the game, I noticed some textures are all messed up or something. There are these huge yellow polygons everywhere, replacing certain objects like stalactites and rocks, and Celebro is a big yellow polygon with a grey exclamation point on him. I also took a third-person view of my character and he has one on him too!

Also, there's no voice acting, and the text goes through extremely fast, too quickly to read. I've been through the story before so I guess its not a big deal but it'd be nice to be able to read what people are saying.

EDIT: I read through the forums more and noticed others having this problem (with the yellow boxes) However if its because the installation failed, how do I fix that? I've already reinstalled oblivion and nehrim 5-6 times in getting this to work.

Alright mate u gonna listen me now boy. Delete everything and by everything I MEAN fcuking everything. Install a fresh oblivion and patch it to the latest version. Make sure if you have Windows 7 or Vista install it somewhere else outside the Program FIles map. Then you install Nehrim also somewhere outside the program files map. Also update Nehrim and it should work fine!

When I try to uninstall Nehrim, it says it's not in the right directory! Can I just move to recycle bin and delete, or will this leave files on my computer that will corrupt future installations?

EDIT: Cleaned everything off as best as I could. Created a new folder directly in C:\ named Oblivion. Installing into C:\Oblivion. When that is done I'll update with whether the Nehrim installation gives me trouble again.

ok boy this is what u gonna do. U can move it to the recylce bin. After that download cc cleaner. Its a programme which will clean up everything that is left from the mod inclluding registry files. So when u have cc cleaner just open it and go to registry tab. There u scan and fix the selected issues. hope this is clear sonny boy

Got CC Cleaner, Cleaned out all my stuff.

Reinstalled Oblivion to C:\Oblivion.
Patched Oblivion.
Installed Nehrim.

Same problems with yellow boxes, and missing voices/too-fast text.

EDIT: Could this have something to do with the fact that, to get the installer to recognize where the Oblivion.exe file is, I have to delete the \Nehrim off the end of the path? If I let it create its own folder WITHIN the Oblivion folder, it won't let me, so I have to let the files extract directly into the folder, could this be causing any problems....?

Do you have the steam version of Oblivion? You're supposed to install Nehrim in a separate directory so that means not in the same place as Obliviion's . The Nehrim installer should detect where Oblvion is and copy the necessary into the Nehrim folder.

I don't have the steam version of Oblivion, no.

So when I install Nehrim, I don't change the install path, I only change the install path for Oblivion itself?

Also, could a problem be that Oblivion doesn't seem to recognize my video hardware? (when I run from the oblivion launcher it does it's auto-configuration and it says it cannot recognize, and sets to Medium quality)

Don't get confused. Just make sure you don't install Nehrim in the same path as Oblivion. See it as a separate game. You wouldn't install that on top of another game. So install oblivion in for example C/Games/Oblivion and Nehrim in C/Games/Nehrim. It's separate and supposed to be that way. When you install nehrim it will copy the necessary files from Oblivion in order to work.
