Hi J,
Only Developer Edition, Sandbox, and Trial organizations have the ability to create, edit, and delete Apex classes and triggers directly in the Salesforce CRM user interface. Unlimited Edition and Enterprise Edition production organizations can execute Apex and can view Apex in the user interface, but modifying Apex in the user interface is not allowed.
Create new developer org and install it in.
