Install and Activate

Using ChemDoodle requires two setup steps:

  1. Installation
  2. Activation

Installation of ChemDoodle should be done by a system administrator (or yourself if you control the computer), and will make unactivated ChemDoodle available to all users on your machine or network. The administrator should install ChemDoodle, but SHOULD NOT activate ChemDoodle on the administrator account.

Activation of ChemDoodle is done per user, by the user, and will allow that user to use ChemDoodle unrestricted. Activation is done when the user opens ChemDoodle the first time.

Common installation and activation issues are discussed below.

Solutions for common installation issues can be found at the bottom of the installation instruction pages.


Firewall Issues
If your firewall blocks internet connections from Java applications, then ChemDoodle will not be allowed to connect to the internet. An administrator should set up a special exception to allow ChemDoodle to connect to the internet, at least for activation. We apologize, but there are no exceptions to our activation procedure.

Proxy Issues
If you use a proxy to access the internet, ChemDoodle will use the default system proxy information to connect to the internet. If that fails, then you will need to manually define the proxy settings in the proxy.config file that is located in the config folder in the ChemDoodle installation folder.
