Dreamweaver CS6 crashes on start in Yosemite

[chapinpark]

My apologies if this has been discussed elsewhere, but I've been searching the forums here and elsewhere without finding a solution. I've recently done a clean install of Yosemite on a computer, and found that a copy of Dreamweaver CS 6 downloaded from my university will not open. Puzzlingly, I've done the same sort of Yosemite install on another computer, and Dreamweaver (same version, downloaded from the same site) does open on that one. I have made sure that Java and Flash are installed on the computer, as some others indicated that that might be the cause of the problem, but that has not made a difference. I know that this is not much to go on -- but any ideas would be appreciated.
