Question:
An error occurred in the application created by Plex  due to the contents of the obax.lic file being different.
ERROR:"Control Name : The runtime licensing key is missing for this control".
Answer:
The obax.lic file is created and updated under the Plex product folder when opening a panel with the corresponding local model and control in Plex.
Add the entry for this control as described in "Adding Entries to ObAx.Lic" n the Online Help..
Additional Information:
"Adding Entries to ObAx.Lic"
There are two ways of ensuring that the ObAx.Lic file contains the necessary entries:

Open your model in CA Plex and then open each panel containing a licensed ActiveX control (again, you only need to open one panel per each type of control, not for every single occurrence). This automatically registers each control’s license key. 
Run the application on a PC that has the license files supplied by the control vendor. Open every panel that contains each type of licensed ActiveX control (that is, if two or more panels contain the same control, you only need to open one panel). This automatically registers the ActiveX controls license key in the ObAx.Lic file. 
Having prepared the ObAx.Lic file using either of these methods, distribute it with your application along with the other run-time components listed in this chapter.

Note: ObAx.lic files created with releases of CA Plex earlier than 3.5 should be recreated to ensure that they function correctly.
