Please note: The scientific software platform that owns and administers ChemDraw, previously known as PerkinElmer Informatics, has recently undergone some changes and has been rebranded as Revvity Signals Software, Inc. This change does not affect our access to ChemDraw or the download and installation process outlined below.

1. New Users: Click here to register using your University of Toronto email address

2. Once you have completed your registration, you will be sent an email to verify your account. The email will have a Verify your Email button.

3. You will then receive an email to create your account. In the email, click Create Account and you will be brought to the RevvitySignals Download Centre sign up page. 

4. Sign up for the Revvity Signals Download Centre. Use University of Toronto as your company name, your UofT email that you used on the first registration page for the email and create a new password.

5. Once you have signed up, you will receive another email to confirm your account. In the email, click Confirm my account and you will be brough to the RevvitySignals Download Centre log in page.

6. Log in with you UofT email and the password you just created.

7. Once you have logged in, you will be taken to the List Entitlements page. Click on the first Download Now link listed next to ChemDraw Professional.

8. On the next page, copy the activation code highlighted in yellow as you will need this after you install the software. Then click on ChemDraw Professional from the New Versions tab to install the latest verson. Download the Mac OS installer (.dmg file) and complete the installation process.

9. Upon opening ChemDraw, a pop-up window will appear providing different options for licensing the product. Choose Activation Code and click Continue. If you are only able to enter a Signals URL and do not see the option to use an activation code, this means that you are opening the wrong application. Please make sure you are opening ChemDraw, rather than ChemDraw Collections (see Step 4 above).

In the new window that appears, enter your name, U of T email address and the 16-digit activation code you copied from the Revvity Signals Download Centre in step 3. Select Activate or Deactivate online, then click Activate. Now your license has been activated and you can use ChemDraw!

If you encounter an error when downloading or installing the software, please check our FAQ and Troubleshooting page to see if your problem is addressed there.
