QA is for version 2015. but you have activated the 2016 version, so that version is the ‘active’ one.
The error in version 2016 is because it’s not the right license info, the error in version 2015 is because that version is upgraded when you entered the license info in version 2016. It deactivates the older and the older version can only be activated on machines where it was once installed…
Do another search in the mailbox with the full serial number and replace the ‘Q’ for an ‘R’
that should pop up the 2016 license info ( All licenses have different authorisation codes)
