Buried is correct. Sometimes it doesn't show up. And searching for info on LR on the website seems to always point to the CC version. It's like Adobe doesn't want anyone to know there is a standalone product.
It's no problem – you can always use the LR6 direct links to download instead:
Those work for either the CC subscription version or the LR6 standalone/perpetual version. Those links will also give you offline installer files that you can back up, or store on portable media for use on multiple computers, use as a fast free trial wherever you are, etc.
