I'm running Yosemite (10.10) BUILD 5. I called Adobe Tech Support. They said Dreamweaver 2014.1 would not work with this version of Yosemite. (The prior version worked fine.)
No error messages at all. It just will not launch. It does nothing.
The woman in tech support took over my machine and concluded it was a Yosemite problem.. I think Apple is releasing Yosemite later this week so I hope it's an issue Adobe resolves quickly.
Thanks for the response...
