I'm using these two functions:

function GetFileVersion(file_: string) : int64;
var len, hnd : dword;
    buf      : string;
    pfi      : PVsFixedFileInfo;
begin
  result := 0;
  len := GetFileVersionInfoSize(pchar(file_), hnd);
  if len <> 0 then begin
    SetLength(buf, len);
    if GetFileVersionInfo(pchar(file_), hnd, len, pointer(buf)) and
       VerQueryValue(pointer(buf), '\', pointer(pfi), len) then
      result := int64(pfi^.dwFileVersionMS) shl 32 + int64(pfi^.dwFileVersionLS);
  end;
end;

function FileVersionToStr(version: int64) : string;
begin
  result := IntToStrEx( version shr 48           ) + '.' +
            IntToStrEx((version shr 32) and $FFFF) + '.' +
            IntToStrEx((version shr 16) and $FFFF) + '.' +
            IntToStrEx( version         and $FFFF);
end;
