ZEMAX runs under Windows™ and Windows XP will run on Intel-processor based Macintosh computers via Boot Camp or Parallels Desktop. ZEMAX has been tested with Windows XP under both of these platforms. If you attempt to run ZEMAX on either of these platforms, it is highly recommended that you install the latest version of the respective software (Boot Camp or Parallels Desktop).

If you have a parallel port ZEMAX key, you will need to exchange it for a USB key as Macintoshes do not have a parallel port.

Please note that ZEMAX Development Corporation cannot provide support on installing Boot Camp, Parallels Desktop or Windows XP on your Macintosh computer.

Once you have setup XP under either Boot Camp or Parallels Desktop, you can install ZEMAX on your Macintosh using the normal installation procedure: see How to install ZEMAX for the first time.
