I feel that your VP for UML installer atleast for windows should ask the user if he or she wants to install jre(Java Runtime Environment) to his/her computer. I tried to install the program with windows installer, but when I noticed that it was about to install another jre to my comp I aborted the process. I develop java programs so I already have two jre’s in system.

another point (bug??) when I aborted the install process installer program went to a state where it didn’t reply to systems calls, so I haved to use taskmanager for shutting it down… My comp is running on win xp pro
