As Ben suggested user specific deployment is not supported. For your scenario and activation need, there is a workaround which should make it work -
To publish globally we write scripts in the Machine scripts section in the deploymentconfig.xml. To resolve your case create the same script extension points (as done under MachineScripts) by adding the script calls inside UserScripts section in the Userconfig.xml (for script details please refer to Post Sequencing section: http://www.stage.adobe.com/devnet-docs/acrobatetk/tools/AdminGuide/appvacrobatDC.html#post -sequencing-steps)
However, this is untested and supported scenario and hence there could be certain functionalities that might not work.
