When you are using the latest version of the Components Manager the developer licenses serve no purpose anymore and you can ignore this explanation.

It would say not.

It is far easier and better to take the original file that was sent to you (or your co-worker) and use the IT2BE Components Manager to install the developer licenses.

When you do not yet have the Components Manager installed you can download it here. 

Do not forget to download and read the manual as well!

When you really must copy manually you have to make sure that you copy all files and folders that start with 'it2be-' like: your_servoy_folder/application_server/beans/it2be-* and your_servoy_folder/application_server/plugins/it2be-*
