Do I have a 32bit or a 64 bit version of Windows?

If you are not sure, which version of the operating system is installed on your machine, click on:

  • (Vista:) Start → Computer → System Properties (right mouse tab) and check the information about the System type

  • (Windows XP and 2003:) My Computer (right mouse tab) → Properties → General: The 64 bit versions have an entry there, which reads: ” .. x64 Edition” → Shortcut: Just click on the 'Windows-key' and 'Break' to get to System Properties
