Hello,

I have a project in OCaml. It is used mainly in a Linux environment, but it happens that I need to run the executable generated in a Windows server.

I remember vaguely that, several years ago, I could compile the project by `ocamlc` and generate `project.exe` in Linux, and copy paste `project.exe` to Windows server and it worked.

Today, I repeat this process to the same server (Windows Server 2012, 64 bit), running `project.exe` in Windows server gave me an error `Unsupported 16-Bit Application: This version of C:\project.exe is not compatible with the version of Windows you are using. Check your computer's system information and then contact the software publisher`.

Could anyone tell me if this approach is wrong? How to fix this?
