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 older versions

After November, you can no longer renew your subscription for versions 14 and 15 with these instructions and must request from Cambridgesoft, via the support ticket , a serial number/reg code 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 ChemBioDraw window should then appear.  

2. Go to "Help" on the toolbar

3. Choose "Activate ChemDraw"

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 Ultra" instead.  The new date should be next November.


If you encounter an issue when renewing the software, contact Patricia Meindl,, for assistance stating your operating system and your ChemDraw version.
