The above is such a boiler plate answer and is ridiculous. 

You do NOT have to buy another subscription. If you purchased the Photography plan subscription that includes Photoshop and Lightroom Classic.

First thing to do is restart your system. Then open the Creative Cloud Desktop app and see if LR Classic now says Install. If not then use the CC Cleaner tool to remove All Adobe software and then reinstall fresh and see what happens.

This is Not an Account problem. It is a problem with your system, in some way.
