Ben, that is the same version I have at my office which is working. I'll have to check what was installed at the home office tonight. The frustrating thing is, the home office was a fresh install (entire OS, as well as entire Adobe CC install)... so the version I have must be the most current. It has to be the order in which I have them installed. My office system, I had the same results when I uninstalled 2014 and suddenly the 2015 started working (extension manager that is).. then when Ray posted that updated extensions were available I had no issue installing. On the home system however, there has never been a 2014 installed since complete system re-install occurred yesterday. So... I'm stuck with a fresh clean install of 2015 and Dreamweaver nor others showed up initially. I deleted the .db file as Ray suggested, and that caused apps such as Illustrator, Flash and a couple others to appear in the manager.. however still no Dreamweaver. I've uninstalled, reinstalled in various orders.. I'll have to check the version number when I get to the home office later this evening.
