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 PCs

ChemDraw 20 is the newest version. Versions 17-20 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.
