Creating Environment Variables to define Courses and the Codebashing Platform
You need three mandatory system environment variables. An additional three optional system environment variables can be created for the name and the description for the generated courses.
Navigate to the System Properties dialog. Getting to the System Properties dialog depends on the Windows version in use. The System properties are referred to as Advanced System Settings and are for example accessed as follows.
Under Windows 10, System Properties can be accessed via the :About: About menu under Settings and System.
Under Windows Server 2012, System Properties can be accesses via Control Panel > System and Security > System.
Click <Environment Variables>. The list of existing environment variables appears.
To define a new environment variable, click <New…>. The New System Variable dialog appears and you are asked to enter the Variable Name and the Variable Value as illustrated in the tables above.
When done, click <OK>. The new variable is added.
Notice
After updating environment variables, you have to restart the 
CxJobsManager service for the post script action to work properly.
