My old machine gave up the ghost after many years of good service. I bought a new much more powerful machine. I installed Mezzmo in the D:\Mezzmo folder. While moving the databases over and editing the .ini file I thought that a good option to have in the file is an $INSTALL_DIR= variable. That could be used in all of the places that are currently fixed to a path. It would make it simpler for people to relocate the system without making mistakes in several places.
