I have purchased The Works Limited, after installation, i just realize that i need the OPC-COM module, so bought it in market place.

I got the CD Key, i activated it, but then The works Limited License revert to Trial, except the OPC-COM Module.

When i activate the The Works Limited License, OPC-COM module revert to Trial.

I know im doing wrong here, so let me know how to solve this.

You are not doing anything wrong. Your Works Limited key needs to be updated to use the OPC-COM Moduule. Open a [support ticket](https://support.inductiveautomation.com/?/Tickets/Submit/RenderForm/2) and let them know the keys involved, and they should be able to help you out.

Hope this helps!
