I am trying to activate ChemDraw v20.x (or above), but the Activate button is grayed out, even after entering the Name, Email, and a valid Activation Code. How do I get the Activate button enabled?


You can check this by clicking the "Deactivate" button. After the deactivation process, the "Activate" button enables, and the "Deactivate" button is in the disabled state.

If you still run into any problems, please visit to submit a ticket (or send an email to, to get assistance from our Tech Support Team.

To expedite a response to your issue, also include the activation code you are trying to activate along with the Host ID of your machine. You can get Host ID in the following way:
1. Open ChemDraw application (if that is installed already) or while installing the product on their machine, it will open the "Activate ChemDraw" window (otherwise select “Activate ChemDraw....” from the ChemDraw menu).
2. Select the “More Options” button found at the bottom of the pop-up dialog box.
3.You will find the Host ID field just above the "License Details" and "Log" button.
