• To download the most recent version, click the “New Versions” tab, and select the Download Package link. If you need to download an older version, click the “Prior Versions” tab, and select the required version.
• On the Download page, scroll down the page and select the correct download option for your type of Operating System (Windows or Mac). For Windows, ChemDraw Professional has 2 installers – ChemDraw Desktop and ChemDraw Applications. ChemDraw Prime only has a ChemDraw Desktop installer. There is only one file for all Mac installers. To start the download, select the corresponding file name from the “File Name” column.

Once the download has completed, use the following steps to install and activate the software:

For Windows, select the installation file and run it via double click
Note: during installation, if a previous version of ChemDraw/ChemOffice (v17 and up) is detected, the installer may not prompt you for activation. If it does not ask for activation, then you are ready to run ChemDraw.

• If the software does ask for activation, use the Activation Code you recorded from the “List Entitlements” page.
  In the ChemDraw application:
  a) in the Licensing window, select “Activation code” and click “Continue”
  b) in the Activation window, enter the required details such as your “Name” and “Email”. In the “Activation code” field, enter the 16-digit, four-part code you recorded on the “List Entitlements” page above. Finally, click the “Activate” button.
