ChemDraw installation and renewal

A how-to guide on installing the latest version of ChemDraw and how to renew each year in November.

Chemdraw installation for Macs

ChemDraw 19 is the newest version. Versions 17 - 19 use a different account package called Flexnet to track your serial numbers and allow you to download the software.

If you had a login for the Perkin Elmer webpage for version 16, you must create a new registration for Flexnet - you can reuse the username and password if you want.

1. Register  - you will be sent an email to create a password. If for some reason you do not get the email, you can click on the "Existing user" tab and use the Password Finder option to force another email.
