So I've been trying to get FNV to run with Project Nevada today, and I continually get the following error: Project Nevada could not detect the New Vegas Script Extender (NVSE), which is required for correct operation. I'm using FOMM to run the following mods, pointing it to fn4gb.exe as the custom executable. GunRunnersArsenal.esm DeadMoney.esm CaravanPack.esm ClassicPack.esm MercenaryPack.esm TribalPack.esm OldWorldBlues.esm HonestHearts.esm LonesomeRoad.esm FalloutNV.esm More Perks.esm ELECTRO-CITY - CompletedWorkorders.esm ELECTRO-CITY - Highways and Byways.esm Project Nevada - Core.esm Project Nevada - Cyberware.esp Project Nevada - Equipment.esm Project Nevada - Rebalance.esp CASM.esp More Perks Update.esp ProjectRealityMkIv5HDR.esp Lucky 38 Suite Expansion.esp Project Nevada - Dead Money.esp Project Nevada - Honest Hearts.esp Project Nevada - Old World Blues (No Cyberware).esp Project Nevada - Lonesome Road.esp Project Nevada - Gun Runners' Arsenal.esp TGsArmorCollectionVegas.esp Total active plugins: 27 Total plugins: 27 I've also tried running fn4gb.exe directly from the directory (which is an x86 directory, but I have FOMM set up to remove UAC checks, and UAC is disabled anyway on my computer). I haven't tried running NVSE_loader.exe from the FNV directory, but I do have a copy of it there with all the .dll's. Any ideas?
