I am still using Windows XP SP3. So my results may not be what your Windows 8.1 64 bit is doing.
I had completely forgotten the Wizard.
I setup a CM15A with AHP and two LM465 Lamp Modules. One the older before soft start and the other one had the soft start feature.
Also an older LM14A Two Way Lamp Module. That also can process Extended X10 Messages.
I used my Smarthome 1132CU with Smarthome Essentials to monitor the power line X10 signals.
My Wizard tests found two issues.
The Lamp Test, Macro and Timer tests only controlled the Soft Start module and LM14A. As it was sending the Extended X10 Commands older Lamp Modules do not understand.
The RF Transmission test did not control any RF device set to A1. Tried it on a new RR501 and a TM751.
So it your lamp modules do not ramp On and Off {soft start} the Wizard will not control them. Also when defining an X10 dimmer type that does not have soft start. Use the Older Lamps (No Soft Start) drop down list. The Lamps drop down list is for the newer soft start modules.
My Activity Monitor did show some entries after running the Wizard.
