I moved from a different institution.

If you were previously at another university where you had access to ChemDraw, you should be able to create a new login for the University of Toronto subscription using your new @utoronto.ca email address. Occasionally, you may still experience issues when activating the software. If so, please contact the Revvity Signals Informatics Support for help.

Where do I find the activation code?

My license has expired or is going to expire soon.

Each year in October/November, the University of Toronto site license expires and needs to be renewed. When the license is renewed, you may need to update your activation code.
