PC users renewal instructions for ChemDraw

If you are still using version 16, you should upgrade to the latest version now. Follow the installation instructions.

After November, you can no longer renew your subscription with these instructions and must download a new copy (follow Installation Instructions) which triggers a new serial number/reg code (emailed to you and also found in the "My Downloads" on the Cambridgesoft site) which can then be used to activate the subscription again.

During November:

1. To renew your subscription, open Chemdraw.  You might get this message

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

3. Choose "Activate ChemDraw Professional"

4. The activate window should open with all the fields filled except for Company (optional). click on "activate over internet".

5. Check your new expiry date by repeating steps 2 and 3 but clicking on "About ChemDraw Professional" instead.  The new date should be next November.
