Trying to reinstall Lightroom 6 but it says I need to deactivate on other machines

[howmanypigginnamesdoitry]

I uninstalled Lightroom and am trying to reinstall to my Windows 10 machine  but it is saying I am activated on too many machines. I have only ever used it on this machine. I logged into my account to see what other machines were logged in, and none are. But still it won't allow me to activate it. 
I paid for versions 3 right through to 6 I hope Adobe are not going to stop me using this now to force me into subscription.

That's not it, and Adobe can't force you to do anything you don't want to do.

Here's the answer: Lightroom 6 de-activation: https://community.adobe.com/t5/lightroom-classic-discussions/lightroom-6-deactivation-help/m-p/12915...
