Before AirPlay for Media Center Beta 1 you need to first install Bonjour Print Services for Windows and also required .net 3.5 installed.
I was having this issue too, and I just discovered a workaround.
I’m not sure WHY this is happening, but after the RegisterMCEApp.exe error message comes up, close it & finish the installer, and you’ll find in your install directory (the default is Program Files (x86)thomaspleasance.comAirplay WMC Client) three files, two of which should be DLLs and the other should be a .XML Next, open up a CMD window (search for the application cmd.exe), go into the C:Windowsehome directory, and tell the application RegisterMCEApp.exe to run the “Registration.xml” file in Airplay WMC Client’s installation folder. So this command: RegisterMCEApp.exe “C:Program Files (x86)ThomasPleasance.comAirplay WMC ClientRegistration.xml”
It should now show up in Windows Media Center under Settings -> Start Menu and Extras -> Extras Library. Like other people have described, a firewall authorization dialog might pop up behind Windows Media Center the first time you try streaming, but after that IT WORKS!!!!!!!!!!!!!!!!!!!!!
