RGS Unattended Install Record Option Missing

[RobertW_2]

I just returned from the CCI class where we learned to create an install file for the RGS sender and receiver using the /r and /f1 command line options. This causes the setup to create an .iss file that is used for future unattended install of RGS. I don't recall the exact version used in class, but I am guessing it was pre 5.12. Every version I have tried through 5.2 I get a message that is does not support record and playback mode. Does anyone know what the new process is for doing unattended install of the RGS sender and receiver? The User Guide has the old way removed, but does not talk about the new way. The readme for 5.13 just states that new command line options were added to greatly simplify unattended install, but never goes in to it. Any help is always appreciated.
