REQ: Audyssey MultEQ-X Calibration Software for PC

I am requesting MultEQ-X from Audyssey. This is an AVR calibration app for PC. I looked in the usual places but can't find it anywhere.
Audyssey MultEQ-X
This new software tool gives users the control to calibrate existing and new home AVRs that have Audyssey’s MultEQ room equalization technology built-in, giving users greater control over calibration parameters and more detailed information about their room acoustics.
Decoupling the delivery of technology from the AVR itself ensures that MultEQ-X users are the first to experience many of the improvements and advancements to the MultEQ suite of room correction tools.
