New Windows User, Can't Install Kontakt Instruments?

[Carpenter]

I'm coming back to Windows after several years using OSX. I have apparently forgotten the various methods for Windows. I keep trying to install some third party instruments for Kontakt Player. It appears as though I'm doing everything the install instructions indicate, but I'm not having any luck.

Every time I launch Kontakt Player, I get a "Library Content Not Found. Click Locate To Set The Content." message. I have repeatedly tried to automatically resolve it, as well as directing it to the content manually, but it doesn't do anything to remedy the problem.

Does anybody know what I should do?

Thanks!
