How to get installed appliation using BigFix agent. both with registry and regapp methods will be helpful. thanks

I am using IBM BifFix 9.2 version. I want to pull a report of all installed applications. Please suggest both regapp and registy [unistall key] method.

I had written a analysis using regapp, but I can check only one item, but could not get a full list [array] of installed application.
