How to run 32-bit .exe of Battlefield 4 on 64-bit machine

1. Go to C:\Program Files (x86)\Origin Games\Mass Effect 3\ __Installer\directx\redist

2. Delete all the contents of the folder except for the following files: DSETUP.dll dsetup32.dll DXSETUP.exe

3. Install Mass Effect 3 again.

Note change the Go to C:\Program Files (x86)\Origin Games prefix if you installed to a custom location.

Now, I'm not sure if this actually will work. But the only thing I would recommend to try is to uninstall and install again.

1. Open Origin
2. Right click on the Battlefield 3 cover in Origin
3. The option lowest in the drop menu should be "Uninstall". Click that.
4. When it have uninstalled, try reinstall completely from Origin, no disks.

To download from Origin:

1. Click on the cover of Battlefield 3.
2. A drop menu should appear, giving you the option to "Install".

I hope this will work for you :) And if it does, i wish you luck on the battlefield!
