Lightroom 6 - Phase 1

Adobe made me change my password for some reason so I hastily fired up another computer to receive the email from an older talk talk address which I had used when registered.
The next stage involves where I want the catalogue and picture files to reside but at least I feel safe from accidentally updating the original partition OS to Catalina.
Before I proceed I would like to update Lightroom to the latest possible version. Does any one know where the update to 6.14 is lodged on the Adobe site or has it been removed?
