Now, with the Sentinel key driver and ZEMAX program installed, you are ready to run ZEMAX. You can open ZEMAX by:

  • double-clicking on the ZEMAX icon on the desktop (if present)
  • clicking on the ZEMAX icon in the Quick Launch bar (if present) 
  • clicking on the ZEMAX icon in the ZEMAX Start Menu group

ZEMAX should then open.

If you see this message, make sure that you have installed the Sentinel key driver and that your ZEMAX hardware key is plugged in. Refer to page 2 of this article for information on how to install the Sentinel key driver. Once you have corrected the situation, try running ZEMAX again. 

Error message indicating ZEMAX cannot find hardware key

When you open ZEMAX, you may see a window requesting that you enter your license code like the one below.

Window requesting license code

 If you see this dialog box, your copy of ZEMAX is correctly installed, and the key driver is working properly, but you do not have a license code that allows ZEMAX to run with the key that is plugged in. Take a screenshot of this dialog box (use Alt-Print_Screen) and paste it into an email to support@zemax.com .

Please do not phone for a license code! License codes are complex multi-character strings and cannot be reliably given over the phone. Emailing the screenshot of the dialog box to us is the quickest, most error-free way of getting your license code.
