Sorry people, I'm in error! I repeate all procedure of installation and I got my wonderfull 3 free license! DON'T WORRY BE HAPPY.
So it is confirmed you works very well.
But I confirm my idea, it is no possible ask to pay an Open Source SW.
For me, sorry I'm a old man,
so I think what the only valid license formula is the REDHAT WAY, the software is completely FREE, and you can ask me to pay for a good level of assistence, or service, or also for very targetting SW Add-on.
However, you could clarify that the free licenses are obtained from your profile by redeeming the voucher code obtained when you registered the account for the first time.
