Q

How can I tell if I have a 64-bit edition of Windows or Mac OS X?


A

64-bit applications need a 64 bit edition of Windows or Mac OS X for it to run. 32-bit applications will work on both 32 and 64 bit editions of Windows and OS X.

The simplest way of finding out if you have a 64 bit system is to try installing a 64 bit download from this web site. Alternatively:

Windows

This Microsoft article shows you how to find out whether you have a 64-bit edition of Windows:

Mac

To find out whether you have a 64-bit edition of Mac OS X:

  • Click on the apple symbol in the top left of the screen and choose "about this Mac".
  • You will be shown a dialog showing you the OS X version and processor type.
  • As long as you have a version of OS X that is 10.5 or greater, and you have a 64 bit processor then your Mac is capable of running 64 bit programs. To find out if you have a 64 bit processor go here.
