Do I need to reinstall Clarity for different configurations (I bought new modules/extensions or version upgrade)?

If you have bought an extension or control module license, you will get a new user code for the latest SW version and have to use the version compatible with the user code (if you have it, there is no need for reinstalling).

On top of that in the case of a new control module, reinstallation depends on how you installed Clarity originally (typical, full, or custom installation). If you miss any control module in the System Configuration window, you must reinstall Clarity.
