Son of a gun!  There it is – you were entirely correct!  No link was created in the Start / All Programs hierarchy at install time, but the code sure is there.  I'd love to know why y'all decided to put this tool in 'Common Files' instead of "C:\Program Files\Infragistics\NetAdvantage 2010.3\ASP.NET", but I'm not gonna complain…  Thanks a bunch!

Hello Elizabeth – small problem:  there IS no C:\Program Files\Common Files\Infragistics\NetAdvantage 2010.3\Version Utility.  Pretty sure I did a plain-vanilla install…
