Hi,
This is about it:

var
  hZero        : THandle;
  iSize        : Integer;
  pVersionData : Pointer;
  pFFI         : PVSFixedFileInfo;
  uiQuerySize  : UINT;
  wMajorVersion: Word;
  wMinorVersion: Word;
  wRelease     : Word;
  wBuild       : Word;
begin
  iSize := GetFileVersionInfoSize( PChar( Application.ExeName ), hZero );
  if ( iSize > 0 ) then
  begin
    GetMem( pVersionData, iSize );
    GetFileVersionInfo( PChar( Application.ExeName ), hZero, iSize, pVersionData );
    New( pFFI );
    VerQueryValue( pVersionData, '\'{fixed data}, Pointer( pFFI ), uiQuerySize );

    wMajorVersion := HIWORD( pFFI^.dwProductVersionMS ); // Highest 16 bits...
    wMinorVersion := LOWORD( pFFI^.dwProductVersionMS );
    wRelease      := HIWORD( pFFI^.dwProductVersionLS );
    wBuild        := LOWORD( pFFI^.dwProductVersionLS ); // Lowest 16 bits...

    Label1.Caption := Format( '%d.%d.%d.%d', [ wMajorVersion, wMinorVersion, wRelease, wBuild ] );
  end;
end;
