If anyone is willing to help, I can attempt to provide more information and I appreciate it. I really want this to work, but I just can't seem to fix the problem.
I also used to be able to run ENBs with no problems until now. However since I tried installing the ENB neither the ENB or Reshade want to work. Step 1: Go to and go to downloads Step 2 Then click GTA 4 mods and go to LCPDFR Step 3: Download LCPDFR 1. Some time before, I was able to use Reshade, which also uses d3d9.dll, with no problems. Launch GTA CE Atleast once before doing any of these steps. But with it, the game simply refuses to launch, not even coming up on Task Manager. If I delete this file, the game launches successfully with or without mods on any version. I've narrowed the culprit down to d3d9.dll, the main file for the ENB.
After trying many different things, such as patching the game to 1.0.4.0 (from 1.0.7.0), completely uninstalling and reinstalling GTA, deleting and replacing various files within the game's directory (I have been using backups each time I change the files), updating my drivers, updating DirectX, and so on. Launch GTA CE Atleast once before doing any of these steps. So I've been trying to install an ENB (NVIDIA ENB 3.0) to GTA IV on Windows 10 for a few days now with no results, as the game simply refuses to launch. Hello! I just joined to see if anyone could help me with this very frustrating problem.
