How many licences I need?

OK. here is my story:
I have 5 computer at moment, which is 2 for work, 2 for home and one for kids.
their are all PCs,and use different OS.

3 of those PCs have ESS4 which is 3yr 3pc key. which still have 2yrs to go.
I need 2 more licenses, anyway.

recently I bought a new Macbook Pro.I love it, but I still need use window OS for work. So I have a solution from Apple is either use Bootcamp to dual boot or use virtualisation apps like I used on PC.
option are VM Fusion 3 or Parallels Desktop 5.0.

VM Fusion 3 have good support for OS other than windows and Parallels is good for speed and gaming. So I bought VM fushion and going to try Parallels.
also I have the Bootcamp tri boot(Mac OS X/XP/Win7) as well.

1. For additional 2 PC can I add 2licenses to my old 3yr3pc licenses or I need new licenses?

2. I know if I build a new window virtual machine on Mac I need new ESS 4 license for it.but if I clone one of my PC to a virtual machine do I still need a new license for it or just use the one I used on that PC?

3. Do I need individual license for tri-boot OS windows XP and win7 on the Mac or they can share one?

4. If I have a PC have XP Vista and win7 3OSs on it, do I need 3 licenses or they can share one?

Great thanks to anyone can answer those questions.

 

Hello dexteryogl,

To purchase new licenses or discuss possibly adding licenses I recommend contact your local ESET sales representative. They would be able to answer that question more accurately for you.

As for a multi-boot machine running multiple operating systems, are you only able to run a single OS at a time?

Thank you,
Richard
