How Can I determine the version of Lanpak I have installed?

From the \softrak\system directory, run the chksys.exe utility. After the initial check is done, there is a button that determines the Lanpak Status. It will list all lanpaks of all versions installed.

If you don't see a Lankpak Status button, then you need to get a more current copy of the chksys.exe utility, which is installed by any Adagio program.
