Photoshop CC, installes extentions don't show in windows/extension menu. Extensions do show as installed in Extension Manager.

Question

Can I export extensions?

Answer 1

I didn't want you to reinstall Extension Manager, I just want you to reinstall the extension with Extension Manager then remove the extension.
Please try to run EM as administrator firstly.
1. Run "/Applications/Utilities/Terminal.app".
2. Input the following command then press "Return" key. Don't miss the double quotation marks.
   sudo "/Applications/Adobe Extension Manager CC/Adobe Extension Manager CC.app/Contents/MacOS/Adobe Extension Manager CC"
3. Input password of administrative user then press "Return" key.
If it works, you can try to run EM in normal way.
If it doesn't work and you have installed only few extensions, you can simply delete "/Library/Application Support/Adobe/Extension Manager CC/Configuration/DB/ExMan.db". After that Extension Manager shouldn't hang anymore but all extensions you have installed will not be shown in Extension Manager, although they still work fine in DW. You can install them again if you want to manage them.
If you don't want this way, you have to generate log files for troubleshooting.
1. In Terminal window, run the following commands in turn:
   cd ~/Library/Application\ Support/Adobe/Extension\ Manager\ CC/
   mkdir Log
   cd Log
   touch ExManCoreLibLog.YES
2. Open Finder, hold down "option" key, click menu "Go"->"Library" to go into hidden Library folder, then go to its subfolder "Application Support/Adobe/Extension Manager CC/Log", check whether file ExManCoreLibLog.YES exists.
3. Launch EM.
4. After EM hangs, force quit it, send the log file in the Log folder above to [email protected]
