Reactivating ChemDraw

Those who are currently using versions 10 to 15 should need only “reactivate”. To reactivate, click “Activate ChemDraw…” on the “Help” menu then select “Active over internet”.

If you need your serial number and misplaced it, you can look it up by logging in on and clicking “View Serial Numbers & Expiration Dates for Your Downloads” “My Downloads”.
To download v15, go to here and follow the instructions to download.

If your current serial number will not activate, go to the website here. When you reach the download page, you should receive an email within a few minutes with a serial number that should work.
