Connectivity RTD Server Configuration Elements
If you needed to change the connectivity configuration in order to develop your solution, you will also need to make sure that the same connectivity configuration is in effect for your users.
The connectivity configuration data for the Connectivity RTD Server is stored in the following file (optional):
The <CommonApplicationData> folder is the directory that serves as a common repository for application-specific data that is used by all users. Its actual location depends on your system; it can be e.g. C:\ProgramData.
Most likely, you will not create this file manually. You will rather take the connectivity configuration file from the computer where you have developed your solution, and then place it onto user computers.
