Just a couple of comments:

If instead of using InstancesOf you use a ExecQuery, then you can filter the name of the program directly in it, and WMI will do a case insensitive search of it, for example:

loCIMV2		= GetObject("winmgmts://localhost/root/cimv2")
loProcesses	= loCimv2.ExecQuery("SELECT * FROM Win32_Process WHERE Name = '" + lcExe + "'")
For Each objProcess in loProcesses
	objProcess.Terminate(0)
Next

The where clause will work no matter what was the actual "case" of the application instance, making it, IMO simpler.

The other comment is about the number of instances, if multiple instances of the program are running, but you only one to kill one, using the name is somewhat random, so I think that, for lack of information (for example Process_id) is better to terminate all processes. Of course that is just my opinion.
