MephistoVI

I've been searching and searching, and all I find is old topics that say to do things that do not work (already done them and still getting the same errors.) It says I am missing steam_api.dll, binkw32.dll, and libvorbisfile.dll in that order. Those three files are in the main Fallout New Vegas folder (installed to default location C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas). I am using NVSE, the 4GB Fallout New Vegas file, and have everything as up to date as it can get, including Fallout New Vegas. The game played fine for quite a while, but in the last two weeks it started throwing those errors at me. The only change made around that time was upgrading to Windows 10 a month prior. Still played fine even after that. Directx says its up to date, so I don't think its that either. I have set nvse.exe, FalloutNV.exe, and fnv4gb.exe to run as admin, and to windows 7 compatibility. Any other suggestions?

looking at the image you posted, i noticed in the file path the name Corel and videostudio it appears (its at the very edge of the file path and is cut off). Did you recently install anything by Corel? If so, it appears a feature in that program has made a change Oblivion does not like, and probably is a sound codec used by the Corel software. This would be something I would check out. Also, if you've been getting a CTD (crash to desktop), check the even log in windows. If it is indeed a bad codec, it should be listed in the event log, usually as the faulting module.
