BEFORE YOU START:

1. It is important that you do not plug in your ZEMAX hardware key until you have been told to do so later on in this article. You should also disconnect security keys for any other software that you have while installing ZEMAX.

2. This article refers to installing the single-user key. If you are using the multi-user network key then see this article instead.

When installing ZEMAX on a computer for the first time, you will need to download two files from the Downloads page of our website. The two files that you will need are the ZEMAX program itself and the Sentinel key driver.
