Activating Developer Kit
From OriginLab Wiki
 The Developer Kit in Origin/OriginPro 8.1
The Developer Kit in Origin 8.1 will be installed as part of the Origin/OriginPro installation. However, before you can access to the Developer Kit, you need to obtain a valid license from OriginLab to activate the Developer Kit. The license is only available for users who own Maintenance.
When Origin/OriginPro 8.1 is patched, the Developer Kit files will be automatically updated at the same time.
 How to Activate the Developer Kit
After obtaining the valid license for the Developer Kit, please follow these steps to activate:
- Select the Origin menu item Help | Update Module License.
- Enter your license in the pop-up window (you can copy and paste).
- Click the OK button. A message pops up to infor you that Origin needs to be restarted.
- Restart Origin.
Note that the above procedure adds a separate license file for the Developer Kit in the same folder where the Origin license is located.
