The U of T ChemDraw site license is renewed annually in October, meaning that you may need to renew your software each year by following the instructions below.
Please note: PerkinElmer and Revvity Signals are now two separate companies. As part of this transformation, all versions of the ChemDraw software that contain the PerkinElmer name are no longer available or supported as of March 25, 2024. This includes all versions before 23.0. If your device does not support version 23 and onwards, please contact Madeline Gerbig at maddy.gerbig@utoronto.ca for assistance.
If you are being being prompted to renew your software, follow the instructions below:
1. Open ChemDraw. You may get a message saying your subscription needs to be renewed. Close any pop-up notifications about renewing your software. Your ChemDraw window should then appear.
2. Open the Activation window from the menu along the top of your screen.
Windows: Click Help > Activate ChemDraw
Mac: Click ChemDraw > Licensing
3. Choose Activate ChemDraw.
4. The activate window should open with all the fields filled. Leave this window open while you retrieve the activation code from the Revvity Signals site, if it doesn't already appear in the activate window.
5. Log in to the Revvity Signals Download Centre (where you downloaded the software originally). Please note: Revvity Signals recently updated their login system. If you already have a Download Centre account associated with your UofT email address, you may need to sign up again as a new user. Visit the login page, click the New User tab and then enter the username and password you previously used to log in.
6. Once logged in, the newest renewal will be listed first on the homepage. Copy the Product Activation Code on the right-hand side.
7. Go back to the your ChemDraw screen, enter the activation code and click Activate. This will renew your access for another year. Note: For Mac users, you may have to first click the Deactivate button before you can activate the license for this year.
Unsure whether your software has been successfully renewed? Check by following the instructions below:
1. Open the About ChemDraw window from the menu along the top of your screen.
2. Confirm that the expiry date listed is October 29, 2025.
