This is another official mini-guide of how to run your game in compatibility by Bethesda. Some people have reports of this method working however, and making their game run so I’m including it in here. This method I found to make the problem worse.
Launch the game through the FOSE launcher. Drag “nvac.dll” into your Fallout 3’s “FOSE” folder. If this folder alreadyĮxists due to other mods, disregard this step. With your Fallout 3 “Data” folder open, create a folder called “FOSE”. Within the NVAC ZIP, navigate to NVSE > Plugins Install FOSE by dragging the zip files contents into your main Fallout 3 folder (FOSE HERE)
Obviously, this method will require you to use Fallout Script Extender, which is why I said if you’ve never modded the game before, it’s almost essential to read that section first.
All you have to do is place the mods “nvac.dll” into your “Data” folders “FOSE” folder. The mod for Fallout New Vegas (New Vegas Anti-Crash) is actually backwards compatible with Fallout 3, and works like an absolute charm in situations when the game simply will not launch. If you’ve never modded your game, I suggest referring to the “Optimizing your game” section first, so you have the basic premise of modding/ ability to install FOSE. This ones going to sound far fetched, but it works.
