QnA & Fixlet Debugger should be installable through IEM Tasks
(Installing all of the utilities with the Console came up in the UG/BoF discussions at Interconnect.)
As of the next client releases only Windows will have no QnA with an agent automatically during install. Windows will come soon with the same functionality as the other platforms.
There are tasks on BigFix.me to install the Fixlet Debugger.
I made them for 8.2, 9.0, 9.1, and 9.2
The method I used can be easily used for any version of the fixlet debugger.
