Hello,
There are total of three activation license keys (two from 1 PLUS and one from 1 SINGLE USER lincense).
PLUS license is installed on one PC, and SIngle user license is installed on another.
I frequently run version compatibitlity issue so I prefer to have both versions installed on the second PC
but activation of second license key for PLUS license for the other PC that already has SINGLE user failed.
I appreciate your instruction,thank you for your help in advance,
