Missing Steam_api.dll and Binkw32.dll, can't start game

[Dragomir7]

I've completed modding FNV using F&L and when I start up the game using 4GBFNV, I see the intro cinematics but my mouse disappears and I cannot use either my mouse or keyboard. The menu also never comes up. When ctrl-alt-deleting and clicking on FNV, I am greeted with an error that I'm missing steam_api.dll, then another that says I'm missing binkw32.dll. I've spent so long modding this game and I'm so stoked to play it, but every time I try and load it up, I get these errors. Any suggestions?

There's nothing in the instructions that would cause any files to be deleted, my best bet is that you have an overly zealous AV package that has considered those files as needing quarantining. Whatever the case using the Steam client to 'verify your files' should restore those missing files.

 

After restoring them I would check your system to see what is removing them as it is not the doing of any mod or FNV4GB.

Don't know if you have done it yet, but it saves you some hassle if you make a backup of the game (+DLC) plugins that you presumeably have cleaned with FNVedit, as Steam will replace the cleaned files. Otherwise check that files haven't ended up in the wrong folder (do a search), if so drag them to the root game folder. If they are there and you still get the same error, try running the game as an admin.

Thanks for all your help! I've verified the integrity and re-cleaned all the plugins that were shown as dirty by LOOT, but now when I start up 4GB FNV, I get the error "the system cannot find the path specified." I've tried redownloading and installing 4GB FNV and added the argument "-laaexe .\FalloutMO.exe" to it, but it's still not working.

Does the game launch if you only use the nvse_loader.exe? If not, does it launch if you do it through steam (with the launcher)?

Did you install FNV somewhere in the Program Files folder by any chance?

Again, thank you so much for your quick responses. I appreciate your help extremely. When I try launching with nvse through MO, the same thing happens where I can't control my mouse and keyboard, the menu won't load, but I can hear the music. The error I discovered this time through ctrl-alt-delete was Steam Error "Application Load Error 5:0000065434". I don't know if this helps, but every time I close FNV (through task manager, there's no other way) I hear what sounds like a vibrating tone, like a stuck sound byte, that won't quit until I restart my computer. Any ideas?

Try copying Steam.exe into the game folder as suggested here. For now I suggest you look at trying to launch the base game from the steam client (without any mods whatsoever) and move onto using the nvse_loader.exe if that works.
