BF4 won't launch on 64bit. Please help.

I doubt you have tried "every solution" as the problem would be gone now, but if you listed the things you already have tried it will be easier for us to help you 🙂

My first guess would be that you need to reinstall the x64 bit version of the visual studio c++ redistribution found in the _installer folder.

I reinstalled the game.

I repaired the game.

I installed the latest NVIDIA driver.

I installed the latest Punkbuster.

I installed the all the vcredists

I installed the latest DirectX

I tried running bf4.exe, bf4_x86.exe, bf4webhelper.exe, bf4x86webhelper.exe in Admin mode.

I disabled Origin in game.

I set BF4 to run in x64 in the game settings.

I set the firewall to not scan BF4.

And probably something else, I don't even remember. 

Oh and I don't know if it's relevant, but the  32 bit version launches with no problems. And yes I do have a 64 bit OS.

Also how doesn't it launch? Nothing happens? Error message? Anything out of the ordinary?

Anyways, it could be because of corrupt files. I would probably try scanning harddrive for errors and then delete the Origin cache.

Check Hard Drive For Errors And Corrupted Files

All files can become damaged. This is just the nature of hard drives. Do this for all hard drives that has Windows, Punkbuster and the game installed.

1. Go to "This PC" in Windows and right click the hard drive and click "properties"
   
2. Go to "Tools" and and press "Check"
   
3. Click "Scan Drive" and let it scan for errors.
4. If it finds errors let the program fix them
   (If there are errors it could mean nothing, but it can also suggest that it might be time to format your computer and/or replace the hard drive)
5. Reboot your computer
6. Run the scan again
7. Keep repeating step 3-5 until no errors are found.

Delete Origin Cache

Now it works, I installed Windows Service Pack 1 and it launches, but It takes a loong time loading, stutters even with 130fps, and most of the times gets stuck loading the map. I was thinking of upgrading to Win10, would that solve the problem?

Oh and yeah I already checked the HD, no errors.

You don't have a fully upgraded Windows and yet you blame EA an claim you have tried everything :D No wonder customer support is a thankless job sometimes. And yes if upgrading your Windows is something which you don't do updating to Windows 10 sounds like a good idea.

Does that change the fact that they didn't give a * about this issue? No. And fyi, I updated Windows with windows updater, but for some reason it didn't install Service Pack 1, so I had to install it manually. It's not like I don't update my OS.

And even after updating it, boom another brand new problem, that obviously EA didn't fix.
