Selecting Version to Install on Second PC

I installed BBC Discover, then Core, then Pro on my studio desktop computer (Windows 10, if that matters). We're supposed to be able to install this software on two computers so I've been trying to do a pared-down installation of only Discover or Core on my laptop, to use when I'm composing and traveling.

Although all the samples downloaded just fine, there is no plug-in after the installation app tells me everything has been installed. I noticed that there are *.nks files in the download, so I installed Kontakt Player; and it cannot see those files as anything it can load.

I'm stumped; ideas?
