d3d9.dll file messing up New Vegas!?!

[HotelTrivago]

I wanted to install to an ENB on New Vegas but I keep on getting the d3d9.dll error

[talgaby]

That most often indicates a zealous security software or one of the Nvidia bloatware (or older AMD bloatware).

But how do I figure out where the problems are
also if this helps I delete the dll and everything works fine but no ENBDev stuff is running.
I've tried pressing shift and enter but it doesn't work. ENBs did work before I did a factory reset on my PC so maybe that was issue?

If you got a factory reset, how can you even run the game? It needs DirectX 9, and that is not pre-installed on Windows 10.

At any rate, you can always fall back to this, does the same as an ENB: https://www.nexusmods.com/newvegas/mods/51577

Maybe this can help you.

Cause-1: Win10 has DirectX12 drivers, but the DX9 driver the game is expecting is not being found.

While Win10 comes with DirectX12 installed and is backwards compatible with older DX versions, older games do not know that and are looking for specific versions of DX library files (i.e. d3d9_32.dll) and not finding them. So you need to install the appropriate "DirectX End-User Runtimes" as well: ones which are compatible with Win 8.1+.Note that you need the 32-bit version for 32-bit games.

Solution-1: For DX9, manually install the DirectX End-User Runtimes (June 2010) which is Win 8.1+ compatible. Download the full runtime package. DO NOT use the "Web Installer" version.

Also:

Users of the older version of FNV4GB.exe called 4GB Fallout New Vegas Updated and similar should note that the "D3D9.DLL" file from ENB "wrapper" method needs to be placed in the "Fallout New Vegas\exes" folder, along with the "FalloutNV.EXE" file they moved there when installing that executable. This does not apply to the "injector" method, which requires the "D3D9.DLL" file to remain in the game root folder.

Look at the troubleshooting guide and setup your game as good as you can. Its some work but gets rewarded with a propper gameplay.

Also have to disagree with Talgaby - ENB has more than just the PP effects!! There is also a memory manager (ENBoost) that no one provides like ENB! The linked mod is "only" a PP for effects, to me not as fine as Reshade or SweetFX and surely no replacement for ENB! Just saying :)

Hope you get this going and then Have Fun :)
