Joe,
I believe you're looking for the wrong file name. If you just purchased the Karaoke Suite, you should be looking for khpro4103setup.exe
It should be in the same folder as the rest, ie:
c:\program files\Micro Technology Unlimited is the default folder(if you're installing on c
If you do not have it, then download the one product again, not the entire suite.
Hope this gets it.
