You are not alone : ) , I just solved the "30-day trial" problem yesterday by totally reinstall the OS X, and then I got this new problem WTH : ( waiting for new update from Adobe.
Not sure of PS but to install indesign , Please uninstall your extension manger CC first .
Open Adobe Exchange link and just download ExManCmd for your Operating System (PC/MAC)
Install with ref to this : http://helpx.adobe.com/extension-manager/using/command-line.html
Note:since i have downloded the ExManCmd on my desktop i use below path to execute ExManCmd.exe instead of going to Libray/ApplicationSupport
H-MAC:~ Admin$ cd /Users/Admin/Desktop/ExManCmd/Contents/MacOS
