How can I determine which version of Microsoft Access Database Engine Redistributable is active? I know that multiple versions can be installed. I have been successful in determining which versions are installed (looking for a registry entry) but I don't know how to tell which one is active if there are multiple versions.

I am working on installation software (C++) and I need to install a specific version if it is not already active. I am finding that it is installed but it is not what is actually used. I need to figure out if the one I want is active so I can reinstall it if not.
