The College of Chemistry pays for a UC Berkeley site license for ChemDraw Professional.

Each user must register using an email address at the Cambridgesoft registration page. The UC Berkeley Account ID is: 3663SL

Reactivate: The license expires every year at the end of May and must be renewed/reactivated. You can reactivate for the next year by starting ChemDraw and clicking Activate Chemdraw from the Chemdraw menu and typing the new activation code in the popup.

Activation Code: is under the Order History option on your Perkin Elmer License login page. Click on the Order Number to see the Activation Code.

Password Reset:You can reset a password at:

Download: Once you have registered and have a Activation Code, you can download from the Perkin Elmer License login page.

Old versions: To get codes for older versions of ChemDraw, login at the Cambridgesoft login page and submit a support request.

Group Computers: If you are the system administrator for a group of shared computers in a research lab (College of Chemistry only) or a teaching lab (any UC Berkeley), email us for a "lab" license. This is only for shared computers. Individuals should register individually for licenses for their own computers.

IPad app: not included in our site license. You can buy it from the App store.

Each address can activate 2 copies of each version of the software.

Other issues:
ChemDraw has very specific Operating System Requirements. Do not install until you check these.

For 3D modeling analogous to Chem3D, we recommend Avogadro.

If you are upgrading from different versions of ChemDraw, you should fully uninstall the prior version first. The installer will usually advise you how to do this.

Our site license will not activate any Chemdraw version that did not come from our site license, such as a version of Chemdraw you had at another university or a version downloaded from some other link on the Cambridesoft website.

The College of Chemistry has no IT staff and there are more than a 1000 users of this software. Troubleshoot using the tips here. Verify your machine meets the operating system requirements linked above. To access FAQs, articles, support forums or submit a help request, go to Perkin Elmer support.
