Johnhoe,
Does this mean you always have to start by installing Sonar 2, then uninstall everything except dr-008, and finally install Sonar 3?
What if Sonar 3 is already installed and you need dr-008?
It is this kind of thing I hate. I have several computer programs working this way where you have to do several installs in a certain order, apply patches etc. In fact, I keep a log of the whole setup of my computers, just to remember it all when upgrading the whole system.
