The College of Chemistry pays for a UC Berkeley site license for ChemDraw Professional (version 18.0 as of 11/01/18).

To obtain ChemDraw Professional, you 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. In prior years, you could reactive by starting ChemDraw and clicking Reactivate from the Help menu and typing the activation code. We don't know if that still works. You might need a new code for the next year.

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. You can also reset a password at that link.

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), contact Kathy (below) 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 iTunes.

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.

See the list of Program features.

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.

There are more than a 1000 users of this software and the College of Chemistry has no IT staff. Please try to troubleshoot using the tips here. Verify your machine meets the operating system requirements. For download problems or questions, contact PerkinElmer Download Center Support at or call 1-888-715-4687 (within the US) or 1-408-642-3965 (outside the US).

If you have further questions, contact Kathy Durkin.
