--- Comment #3 from James McKenzie jjmckenzie51@sprintpcs.com 2007-12-29 17:15:46 --- As a suggestion, use ps -aux to find the running installer and then kill -9 (or kill -KILL) pid, where pid is the process id for the installer process. I've done this quite a few times to stop run-away processes under both Linux and Mac OS X.
