Although Extension Manager CC works for us in-house (we're a plug-in developer), we've started seeing a common failure in the field: when people double-click our .zxp downloads, it will go through the installation process successfully, and even show the plug-in is installed, but the plug-in files were never installed in the InDesign CC/Plug-ins/ folder. (So far this is only failing under Mac OS.)
We haven't been able to capture a .log file yet, but we're working on that.
Has anyone else seen this? Any ideas?
Thanks.
