Fallout 4 VR isn't launching

[Mr Pig]

I'm racking my brain trying to figure out why Fallout 4 VR will not start for me. If I attempt to start it on Steam, it flashes "running" for about a second then goes back to the menu. If I launch it in administrator mode, I get the error:

"Fallout4VR.exe - Entry Point Not Found
The procedure entry point
?_Cancel@_CancellationTokenState@details@Concurrency@@QEAAXXZ could not be located in the dynamic link library C:\Program Files (x86)\Steam\steamapps\common\Fallout 4 VR\Fallout4VR.exe."


This is the *only* game that will not run for me- every other VR game works perfectly. I'm running a Geforce 1070 so there's no reason my system should be incapable of doing so.

Things I've tried:

- Restarting my computer (several times)
- Restarting Steam (several times)
- Validating the game files
- Uninstalling and reinstalling Steam
- Uninstalling and reinstalling Fallout 4 VR
- Clean installation of updated graphics driver
- Uninstalling and reinstalling Microsoft Visual C++ 2010-2016
- Reinstalling DirectX
- Opting in and out of Steam VR Beta
- Disabling Avast anti-virus
- Allowing the .exe to go through my firewall

I cannot for the life of me figure out what's going on. If you guys have any ideas what could be going on, please let me know.

Hmm.

Off the top of my head. From the error it looks like there may be a problem with the WinSxS configuration for Microsoft Visual C++ 2012. Missing an entry point in the Fallout 4 VR.exe is most likely an issue with the Visual C++ install or configuration. (Missaligned .DLL's play havok.)

I know you indicated that you have reinstalled the Visual C++ files. The Steam Build Bot would install both the X86 (32bit) and the X64 (64bit) versions of these. Are both the 32bit and 64bit versions installed? Can you manually run the files that are loceted in the vcredist folder?

Also, are you running any ENB's or Reshade's that would be interjecting themselves as .DLL's into Fallout 4 VR?

Can you post your exact system specs as well? Hope I can help.

Yeah I already tried uninstalling and reinstalling Visual C++ 2012 to no avail. I manually installed both the 32bit and 64bit versions from the vcredist folder too.

I am not using any mods.

I'm running an i7-3770 @ 3.40Ghz, 12 GB of RAM with a GTX 1070.

I've only had the game crash for me when altering one INI line, but that's it.

If anyone has any ideas at all, that would be super helpful. I've been dying to play this game on VR and I'm incredibly frustrated it isn't working.

Are you using a vive or a rift? If the vive.....no ideas but If the rift, are you using core2? I had to go back to the old version to get it working. Im sure your already doing this but make sure oculus home is running first, then steam...then steam vr..then fallout4vr, out of that order causes the game to crash for me. Messing with the nvidia graphics cards settings caused some problems for me like crashes. Setting them to default helped.

Beyond that....im stumped.

Yeah I'm using the vive and tried this. I'm also stumped :/

What is in the Windows log files? Your posting shows fallout4vr calling something that isn’t working, but not what was called by file name. Usually this points at a MSVCR110.dll problem. I don’t think this is game related at all, It is MS runtime related, something has changed in this area. What version of Windows are you running, and is it up to date on patches. Check if file MSVCR110.dll is present and what version it is.

I'm running Windows 10. MSVCR110.dll is indeed present but I also suspect something is wrong with it. Is there something I can do to repair the file?

Also, my computer has recently failed to install a Windows update several times. Could that possibly be part of it?

Yes.

You could try the following: grab the DLL from an external source (such as https://www.dll-files.com/msvcr100.dll.html ) and place it with the Fallout 4 VR EXE in the Fallout 4 VR folder. It should load that DLL then, so you can test if it is actually the problem. However, there might be other DLLs providing the hook not found, and as your error message mentoins the Fallout EXE and not the DLL its a bit more odd anyways.

Log in as an admin, running a program as an admin won’t work consistently.

Open a command prompt (DOS prompt for those of us who remember Windows 386)

Enter: regsvr32 (COMPLETE path to msvcr100.dll file) if there are any spaces in the path name, then enclose the line with quotes, I.e.

Regsvr32 “C:\Program File(386)\Steam\Steamapps\common\fallout4vf\msvcr100.dll”
-or, to original 32 bit version
Regsvr32 “C:\progam files(386)\windows\system32\msvcr100.dll”
-or the 64 bit version-
Regsvr32 “C:\progam files(386)\windows\syswow64\msvcr32.dll

If you check the file properties, you should have version 10.00.40219.325 for the 32 bit and the 64 bit. The files names and version are the same for 32 and 64 bit but the 32 bit file is 809kb and the 64 bit file is 755kb.

See if you can finish the updates you are missing as one of the failed updates may have unregistered an old version and not fully registered the new version.

What version of Windows are you running, and what is in the log files?

[Mr Pig]

I finally got it to work!! I deleted msvcr110.dll from system32 then reinstalled visual c++ 2012. Thank you all for the replies!

[dasBenni]

Yay! Game on :)

[chuck]

Sweet!
