College of Chemistry: ChemOffice+ Cloud site license


The College of Chemistry pays for a UC Berkeley site license for ChemOffice+ Cloud with Signals Notebook Individual.
Note that we have licensed Signals Notebook Individual, not the Enterprise version (way more money).

ChemDrawPro is still the main desktop tool and ChemOffice+ adds some extra utilities and is an interface to a cloud based E-Notebook called Signals Notebook Individual.

If you love ChemDrawPro as is and don't need Signals Notebook, then you can skip the steps about Signals Notebook and just use ChemDrawPro as a stand alone program.


Begin Here:

We advise you to not install ChemDrawPro/ChemOffice+ until you check the System Requirements which are in the release notes and related guides linked below.
These links requires UC Berkeley authentication so you must be on the UCB VPN.

Hardware-Software Guide
Activation Guide

Once you know the software will work on your computer, start with the Quick Start Guide
This guide directs you to register at one or more Revvity (formely Perkin Elmer) sites.
Use a berkeley.edu email address when you register.
Starting on page 2, it walks you through the needed steps, but note that the links have changed!!!

We believe these are the current links:

Revvity Home
Revvity Site Subscription
You should search for UC Berkeley at the Site Subscription page and then register and/or login.

Note that there are 2 registrations, one is to download ChemDraw/ChemOffice and one for the Signals Notebook Individual login. You must use a berkeley.edu email address at all steps in this process.


You can input the same credentials for both if you wish but they are separate databases, so if you change the password on one, it does not affect the other.

Once registered to access the Perkin Elmer Cloud applications, you will see 2 cloud tools:


If all you want is ChemDrawPro, you do not have to register for Signals Notebook. Just do steps 1-3 in the Quick Start Guide
and skip to step 7.


Below are are ChemDraw 21 notes. These are probably obsolete since Perkin Elmer has transferred the software to Revvity. But the transition is incomplete so these notes may still have some use.

Signals Notebook:

We have put this Signals Notebook discussion before the ChemDraw Download discussion but if you are not using Signals Notebook, skip ahead.

Once registered to access the Perkin Elmer Cloud applications, you will see 2 cloud tools:


To fully complete the registration, you must click on the link (in the purple shape above) "To access this subscription, Click here." You must click on that link once to activate the Signals Notebook registration.

Here is a YouTube Signals Notebook video.


Download ChemDrawPro:

Whether or not you use Signals Notebook, once you have registered for downloads, use the Revvity Site Subscription login page. Click on ChemDraw Professional on the Download Order page (screenshot). Look under Order History (screenshot) and click on Download Now for the top Order Number.

Here's an image of the download components.

For Mac, download the installer dmg. For Windows, download the installer exe.

On a Mac, ChemDraw and ChemOffice+ must be both dragged in Applications during this installation:

Activate: The installation will request an activation code. This should have been emailed to you or you see it on the Order History (screenshot) page (note it is greyed out on this sample) but it is visible to you when logged in.

Reactivate: The license expires every year at the end of May and must be renewed/reactivated. This might happen automatically. If not, you can reactivate for the next year by starting ChemDrawPro and clicking Activate Chemdraw from the Chemdraw menu and typing the new activation code (see above to look up your order history) in the popup.

Each berkeley.edu address can activate 2 copies of each version of the software. If you had to replace a laptop etc mid year and need a few more copies, login at the Revvity Site Subscription page.


Signals Notebook should now be available from within ChemDrawPro


Other Notes:

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.

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

People on berkeley.edu networks (eduroam, UCB VPN, campus wired connections etc) can download the ChemDraw JS toolkit.

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 Revvity Site Subscription page and login.

If you have further questions, email us.

Please include:
1) Your full name. Are you grad/undergrad/postdoc/staff/faculty? What is your department (Chemistry, MCB etc)? Support is very limited, especially for non College of Chemistry people.
2) What is the berkeley.edu email address for your Cambridgesoft account?
3) Did you login to Revvity Site Subscription and check your records?
4) Did you check the operating system requirements?
5) What is your exact Operating System: MacOS 10.6.1, Windows 10, etc, and what version of Microsoft Office are you running?
6) What is exact version you are using/installing, such as ChemOffice 21 or ChemDraw Professional 20.1?
7) Are there error messages? Include the exact text or a screen shot.
8) Is this is a new installation? Did you delete the old version first?
