When trying to install CNC12, I keep getting this error message:

Aborting, of course, cancels the whole operation, retrying just keeps popping the error back up, and ignoring lets the install finish, but nothing happens when I click on the desktop icon- because of course there's no executable to launch it.
I'm rather disappointed since I spent the extra on the factory-preloaded/preconfigured PC specifically so I would have fewer configuration headaches to contend with.
Any suggestions on how to fix it?
Doc.
