Selecting from multiple Service Desk framework on console startup

I've used the Touchpaper.Tools.AppConfigUpdate.exe to create a multi-instance startup for my console.  After updating the config, I don't receive a dropdown list on the console startup splash screen.  The config file shows the second instance line (<add key="ConfigurationCentreUrl01" value="http://server/second_dev.Framework" />) has been added, yet no option to select it.  Any suggestions as to why?

Using SD 7.7.1.

Thanks
