PerkinElmer has announced that ChemBioDraw Ultra 14 will be replaced by ChemDraw Professional 15. The new version will be available on our download portal at CambridgeSoft in the coming weeks. In order to obtain the new software you can login to CambridgeSoft with your JHU email address. You will need to create an account if you do not have one already. Version 15 can coexist with version 14, so you will not need to uninstall.
