License usage on Mac 10.6 and 10.4

[Sean]

Hi, i really wanted to buy Helicon Focus but i need to clear up my doubts before i do.
I got 4 Mac, 2 of them running on Mac OS 10.6 and another 2 running on Mac OS 10.4, from the website i can understand that 10.6 need to run on Helicon Focus 4.2.1 while OS 10.4 need to run Helicon 4.0.5.
The question is when i purchase on the license, i got 4keys to use on, those keys can use on all version of Helicon Focus i downloaded? as for the Mac OS in the office differ as stated above need to use different Helicon focus version.
