Lr CC vs Classic - can you get both or do you only get one?

Hi there

My laptop recently crashed with the latest windows 10 update. My data was recovered, but I've had to reinstall Lr and Ps as they did a full reboot. I've realised I installed Lr CC instead of classic (which I had previously) - do i need to uninstall Lr CC before I download classic? Do I only get one?  (I'm on the $9.99 plan). There's a few things I miss about the classic which is why I'm leaning towards re-installing it.
