I have adapted the answer on Stackoverflow [1] for D:

// These Windows headers require DMD >= v2.070
import core.sys.windows.winnt : PROCESS_QUERY_INFORMATION, 
PROCESS_VM_READ;
import core.sys.windows.winbase : OpenProcess, GetCurrentProcess;
import core.sys.windows.psapi : GetProcessImageFileNameW, 
GetModuleFileNameEx;

import std.stdio : writeln;

void main()
{
     // 1) Get a handle to the process

     // 1.1) Example - get current process:
     auto processHandle = GetCurrentProcess();

     // 1.2) Example - get process with id 8036:
     // auto processHandle = OpenProcess(
     //     PROCESS_QUERY_INFORMATION | PROCESS_VM_READ,
     //     FALSE,
     //     8036 /* This is the PID, you can find one from windows 
task manager */
     // );

     // 2) Allocate a buffer for the name
     wchar[2048] name;

     // 3.1) Call GetProcessImageFileNameW
     uint bytesWritten = GetProcessImageFileNameW(processHandle, 
name.ptr, name.length);

     // 3.2) or call  or GetModuleFileNameEx
     //uint bytesWritten = GetModuleFileNameEx(processHandle, 
null, name.ptr, name.length);

     assert (bytesWritten > 0, "Error: GetProcessImageFileName() 
wrote zero bytes!");

     writeln(name);
}

Please note that this is Windows only and you need to use DMD 
2.070 [2] or newer.
I'm not on Windows so I can't test it now, but this should be the 
basic idea.
