Schönen guten Abend,

ich lesen via WMI diw "OSArchitecture" Variable aus. Diese Variable zeigt einem, ob es ein 32 bit oder 64 bit System ist. Leider gibt es diese unter z.B.: Windows 2003 Server 32 bit nicht. Da bekomme ich eine Fehlermeldung, dass diese Variable nicht unterstützt wird.

Wie kann ich nun sinnvoll eine generelle Abfrage für alle Windows Betriebssysteme ab XP umsetzen?

Derzeit mache ich es mit try und except. Finde ich aber irgendwie nicht wirklich scharmant. Leider habe ich keine Abfrage gefunden, die die Existenz der Variable prüft.

OSArchitecture = Null führt auch nicht zum Erfolg. Was würde noch Sinn machen?

Vielen Dank im Voraus.

Sven

Sollte mit GetSystemInfo gehen.

oder


und:

markieren

Delphi-Quellcode:

Function IsWin64: Boolean;
begin
  With TRegistry.Create do begin
   RootKey := HKEY_LOCAL_MACHINE;
   Result := KeyExists('\SOFTWARE\Wow6432Node');
   Free;
  end;
end;

ausserdem

und

oder

Diese Lösung fand ich auch sehr cool (WMI).

kuba

Danke euch.

Ich verwende jetzt die Funktion
Function IsWin64: Boolean; Schade, dass es keine direkte Abfrage gibt, die überprüft, ob die Variable existiert. Denn mein Program liest die Werte nur via WMI aus.

Danke nochmal.
