The College of Chemistry pays for a UC Berkeley site license for ChemDraw Professional 17 (as of 09/15/17).

This web page is in transition since the activation process for version 17 is different from earlier versions. Our page about prior versions may be of use but probably not.

In order to obtain ChemDraw Professional 17, you must register using an email address at the Cambridgesoft registration page. The UC Berkeley Account ID is: 3663SL

If you previously registered with Cambridgesoft, you probably already recieved an email with these details. That email contained a link to the new download site and included a password reset link.

Reactivate: The license expires every year at the end of May and must be renewed/reactivated. In the past, it was possible to reactive by starting ChemDraw and clicking Reactivate from the Help menu and typing the activation code. We don't know if that still works for version 17.

Our site license will not activate any software 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. Each email address can activate two copies of the software.

Activation code: is under the Order History option on your Perkin Elmer - Cambridgesoft login page. Click on the Order Number to see the activation code.

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

Each address can activate 2 copies of each version of the software. If you attempt to activate more, it will also fail.

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. Individual students should register individually for licenses for their own computers.

IPad app: not included in our site license. You can buy it from iTunes.

Other issues: See the Operating System Requirements and Program features. For 3D modeling analogous to Chem3D, we recommend ChemDoodle 3D or 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.

Because of the size of the College of Chemistry, we can only provide limited support. Please try to troubleshoot using the tips here. 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.

Please include:
1) Your full name. Are you grad/undergrad/postdoc/staff/faculty? What is your department (Chemistry, MCB etc)? Technical support is very limited, especially for non College of Chemistry people.
2) What is the email address for your Cambridgesoft account?
3) Did you login to Perkin Elmer - Cambridgesoft and check your records?
4) What is your exact Operating System: MacOS 10.6.1, Windows 10, etc.
5) What is exact version you are installing, such as ChemDraw Professional 17.0?
6) Are there error messages? Include the exact text or a screen shot.
