It's absence means you aren't even getting to the point where that gets started, or that NVSE is not installed correctly, or the log file can't be created. The havok log suggests you installed to the "D:" drive, which should get you past any permissions issues, but have you checked that the game folder is set to allow "Everyone" full control? See the "Take ownership of files and get full access in Windows 10" article. (When you create a new folder it inherits the default permissions from the drive (i.e. "D:\"). By default this does not give the "Everyone" group full access, but "Read Only" which means the game can't create new files like logs.) The NVSE logs will be in the game root folder (i.e. "<SteamInstallPath>\steamapps\common\Fallout New Vegas") and named: "nvse_steam_loader.log" (created when NVSE is started as part of Steam "authorizing" and loading the game) "nvse.log" (the "errors" reported by NVSE from mods) "nvse_loader.log" (if you have it working with GECK) There may be some others, depending upon what else is installed. The "loader" logs will be relatively short but tell you that NVSE initialized. See the wiki article "How to read most Bethesda game error logs" if you have a large "nvse.log" you need to trim down to post here. -Dubious- Sorry i'm a tad confused and i'll get to doing that stuff but I don't have a D: drive I only have a C: and all the fallout stuff gets installed to there (Also I haven't installed FO3 or TTW)
