In case you need more info, I'm using a macpro running osx 10.8.5
I also have Lightroom 5, Premiere Pro CC 2014, Aftereffects, Audition, Media Encoder (all CC2014) installed and none of which show up in the extension manager.
Just want to add that I am having the same issue but with different CC apps. I can see PS CC and Premiere Pro CC but need to install extensions for DW CC. Rather than start a new thread I want to emphasize that lordbiggus is NOT alone. Like him, I'm running several other CC apps.
I'm running a Mac Pro with OS 10.9.5
I have the same issue!
Trying to install an add on for DW CC 2014 and it's not showing up in the Ext. Mgr. I have a feeling it's because Ext Mgr will only allow me to install in the C:\Program Files (x86)\Adobe folder and DW is installed in C:\Program Files\Adobe.
Why on earth Adobe always installs its own programs into different places on the C drive is beyond me, but we should be able to change the location where Ext. Mgr installs then!
ADOBE, please help ASAP!
I have the same issue. I ended up opening the CC version of extension from which had the products I needed, then installing the files from there. I still don't know how to retrieve the programs from a different folder. Adobe should provide some type of guidance.
