I have an iMac running OS 10.9.5 and Dreamweaver will not start. I had the Adobe CS6 suite, and never had a problem with indesign, Photoshop, or Illustrator, but Dreamweaver recently would not open. I just installed Adobe CC 2015, and while Photoshop runs fine, the same thing happens with Dreamweaver - the icon in the dock bounces a bunch of times and then quits. I click it again, and it doesn't even bounce. At wits end!
Please try to restore preferences for Dreamweaver and check if it works fine.
If the issue still persist then try to Repair Disk Permissions by using DiskUtil located in Application >> Utility.
After the repair reboot the machine and try to relaunch Dreamweaver.
Please let me know if the issue still persist.
