I am attempting to run a .kit application using TklTk Aqua Batteris-Included distribution.  I have installed the TklTk package, but the .kit file seems to think it is associated with Excel.  The Microsoft Office Trials where installed on the machine out of the box, but I have removed them.  I can run my .kit file from the command line using /usr/bin/tclsh.  I am fairly new to OS X, so I expect there is something simple I am missing.  Any advice?

Thanks in advance!
