This is just an FYI:

RegisterSmartCenterApp.exe resides in a folder named SmartCenter 2.0.  In that folder there is a hidden folder named UpdateAppSettings.  When you run RegisterSmartCenterApp.exe, among other things, it generates an xml file named the same as the GUID lookin' thing you get on the output message line that restates your input configuration file name:

Registered xml file:

C:...>MyApp.xml, 1b3621a0-a634-4bd3-a8c8-7594d03c8369

RegisterSmartCenterApp Successful!

A file named 1b3621a0-a634-4bd3-a8c8-7594d03c8369.xml is created in the UpdateAppSettings folder and a reference to it is added to a file named AppList.xml in the same folder.

Is this information of any use?  Beats me! 

I had a number of failed attempts that were starting to build up and my OCD is much happier now that they are all cleaned up.

 BTW: I had a lot of "fun" trying to list what was in the UpdateAppSettings folder.  I don't know what special hiding mechanism was used but the only two ways that I've found to see anything in there are:

1. the Advanced Windows Explorer search, but only if I started searching for the file name Applist.xml from the root folder of C:  and NOT from within the SmartCenter 2.0 folder.

2. Visual Studio 2008's File/Open File dialog.
