Both games are from Steam on my E: drive

When I get prompted with the install path selection, I choose my steam>steamapps>common>FalloutNewVegas as the location of the installation and I choose Base Game + DLC for installation.

I also did try starting a new game in New Vegas and got past the character creation and moved into Goodsprings for my latest install attempt, but the same thing happens: invisible items and no map marker for the vertibird/cabin.

I'll post an update after I attempt my next install tomorrow or Saturday.

Im having an issue after traveling to the mojave where the only audio thats working is the breathing from sprinting. No noise from jumping or talking to npcs. Any way I can fix this?

I just wanted to say that this is astounding.  Huge respect for what you have achieved.  I've downloaded this for the first time today and have never used mods or mod managers before and your instructions were easy to follow and the install was a breeze.  I fully recognise that this is a beta, though wanted to constructively share the few issues that I have experienced in game.  
Firstly when I get to the New Vegas map, the audio and dialogue doesn't work when I start conversations with them.
There are also a number of NPCs in the area that are not clothed, which is pretty funny but a little distracting.
Finally similarly to when you are building in settlements, the is a green/red dome around a small section of the area when playing.
Again, these aren't criticisms but just feedback - the game is awesome!  

i also have no audio, no subtitles either

Running into some issues on the 1.1.02 build. The setup runs without popping an error, and everything loads as expected, but most NPCs are set to a default T-Pose with no ambient sounds or voiced dialogue. Any ideas?
