dubiousintent Posted January 12, 2018 Share Posted January 12, 2018 (edited) Before you go any further, please see wiki "FNV General Mod Use Advice" article. It was written for people in your position. As to the specific error: see the 'Solutions to Starting the game problems' section in the wiki "Fallout NV Mod Conflict Troubleshooting" guide. I'm betting you don't have the Steam Client running. See specifically 'Issue: Application load Windows error(s) '. If that is not sufficient to solve the problem, please provide ALL the information requested in the wiki "How to ask for help" article. -Dubious- Edited January 12, 2018 by dubiousintent Link to comment Share on other sites More sharing options...
