Most likely you will need to register the LR6 installation under a different email address from the CC registration.
LR6 and LR CC are the same program, just different licensing.
Thank you Wobertc and ManiacJoe You are both correct! I discovered when I went searching that I had two CC accounts - one with one ID and one with another... I was paying double a month for these ,,,arrrrrrrrrgggghhh! This meant that your solutions did not work .
I hate to say this, but I wish Adobe would make registration easier so that idjits like me didn't double up etc. And I wish they would make it easier for folks like me in remote regions of the world where A. Internet traffic is very expensive and metered to the nano cent and B They would make it easier to amalgamate accounts when idjits like me have accidentally created two separate accounts
