Hi

The program now detects almost every version except for windows 2008, and i cannot add it so that it works. Have tried to incorporate code from a previous question here, but i only got it so far that it will compile without errors, but i dont think it will detect windows 2008, any help please?

Regards

@bdLM works like a charm, but what should i do now with the points, since youre using code that was introduced by Geert Gruwen?

@Geert Gruwen, now this question is open to a divide of points, gimme advice please thanks

Add the unit Unit_EEWINVERSION.pas posted by bdLM two posts earlier to the uses clausule

uses
Unit_EEWINVERSION

And then use the code as shown below

showmessage(CheckWindowsOs());

=============================
unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, Unit_EEWINVERSION, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
showmessage(CheckWindowsOs());
end;

end.

Sorry Geert, I never even thought about mentioning the version of Delphi, I only have and use Delphi7, this explains the compiling errors, forgive me for my ignorance...
