After Purchasing Adobe Acrobat with Serial, can't activate it with Adobe ID which has a CC PrePaid Subscription

TLDR: After entering serial number in Adobe Acrobat Pro, it is asking me to sign in to my Adobe id, i do that, and then it says to sign out of 1 of my 2 computers due to the cloud subscription i have, which makes it useless, i bought it so i can have 3 pcs running adobe acrobat.

I have ONE account with BOTH the following:

1. Creative cloud subscription prepaid - PC 1 and 2

2. Adobe Acrobat Pro Version 12 - purchased Sep 2016 - PC 3

Please note the above are under ONE ADOBE ID Account

Steps:

1. I have Creative Cloud on 2 PCs, i have adobe Acrobat DC running on both of them

2. I purchase and download Adobe Acrobat Pro DC with the serial number

3. I install Adobe Acrobat with serial number on PC #3 with no creative cloud software

4. On PC #3 it is asking me to sign in to my Adobe ID to use Adobe Acrobat.

5. i do that

6. Adobe tells me that i need to sign out of 1 of my 2 PCs so i can use Adobe Acrobat

Issue:

7. Why?........... i purchased Adobe Acrobat for $500 USD so i can use it on my 3rd PC!

Why doesn't Adobe realize i have the serial registered under my account so i can use it on my 3rd PC?

This Adobe Acrobat is NOT part of my cloud subscription!

What do i do?

How do i use my PAID Acrobat on my 3rd PC?
