If you installed steam in the default location, c:\program files(x86)\steam\steamapps\common\new vegas.....
You are up against a permissions problem within windows itself.
The program files directory is protected by the UAC (User Account Control).
The NV launcher is attempting to write to your ini file(s) and windows is not allowing it to do so.
There are two simple ways to fix this issue. and a bunch of more complicated ways.
1. Reinstall steam and new vegas outside of the program files directory... i.e. C:\games\steam..etc etc.
2. Turn of UAC.
The complicated methods involve setting permissions to the directories for the installer program, and other windows processes. Not recommended due to the mess that is windows security permissions system.
