ChemDraw installation and renewal

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

Renewal instructions for ChemDraw for both Mac and PC users

After November, you can no longer renew your subscription with these instructions and must download a new copy (follow Installation Instructions) 

During October/November:

1. To renew your subscription, open Chemdraw.  

You may get a message saying your subscription needs to be renewed.

Just close the window with the X - do not click on OK!  Your Chemdraw window should then appear.  

2. Go to "Help" on the toolbar on PCs and the ChemDraw tab on Macs

3. Choose "Activate ChemDraw Professional"

4. The activate window should open with all the fields filled except for Organization (optional). Leave this screen open while you retrieve the activation code from the PerkinElmer Flexnet site.

5. Next you will need to log on the Flexnet page (where you downloaded the software originally)

6, Once logged in, click on the Order History link

7. Click on the top Order Number (the newest renewal) and you will see the activation code on the right hand side.  Copy that 19 digit code.

8. Go back to your ChemDraw screen and fill in the activation code and click Activate. This will renew your access for another year.


If you encounter an issue when renewing the software, contact Patricia Meindl,, (or Sarah Forbes, if you are affiliated with UTSC) for assistance stating your operating system and your ChemDraw version (screen shots are very useful!).
