I'm trying to install NVSE but it won't work. I have it unzipped with WinRar but I can't figure out where it's supposed to go and I'm starting to get frustrated. I keep watching videos but I can't find steamapps or steamdata. Please help!

If you installed Steam in its default location, your NVSE files will go into C:\program files (x86)\steam\steamapps\common\fallout new vegas .

Right now I am going to check to see if that works, either way, you are a god!
