If you are running it off the Boot CD, it will only be on 1 machine at any one time. So you should be ok with 1 copy. Now if you were installing it on each machine and leaving it there, then that would not be ok. You may want to contact Acronis and ask them just to be sure.
They said the phone lines are too busy. So I must chat. Below is a transcript of the chat. They want me to buy 5 packages. Thats crazy, I'd be nuts to do that.
Answer from Acronis:
Please wait while we find an agent to assist you...
All agents are currently busy. Please stand by.
You have been connected to Mohamed Ameen.
Mohamed Ameen: Hello Jack. Thank you for contacting Acronis Customer Central. My name is Ameen and I will be glad to assist you. Please allow me a minute to review your message.
Mohamed Ameen: As I understand, you intend to use Acronis True Image Home 2011 to clone hard drives on five different computers. Am I right?
Jack Bauer: Correct
Jack Bauer: I'm simply replacing 100gig HDs with 750 gig HDs.
Mohamed Ameen: If you intend to clone your laptops, you can use Acronis True Image Home 2011. However, each of your laptops would require a separate license.
Jack Bauer: That's what I thought. Thank you.
Jack Bauer: You've answered my question.
Mohamed Ameen: Have I answered all your questions.? May I close this case for now?
Jack Bauer: Yes, I would not be using it for backup. I would only use it for copying 5 hard drives. I would not want to buy 5 products for $250.00.
Mohamed Ameen: Thank you. I am closing this case for now. However if you need further help, please contact us again and we will be glad to assist you.
Mohamed Ameen: I understand.
Mohamed Ameen: This product has a perpetual license on a single physical computer.
Mohamed Ameen: Refer the following table:

Jack Bauer: Who cares? Why would I want it on my HD? I'm just going to copy the data, not back it up?
Mohamed Ameen: Just to confirm, you intend to clone the hard drive to external hard drives. Also the drives you are trying to clone are internal drives on each of your laptops. Am I right?
Jack Bauer: Internal Drives, yes.
Jack Bauer: Like I said earlier, I'm upgrading 100 gig HDs with 750 gig HDs.
Mohamed Ameen: Jack, if you intend to clone internal drives, then the software has to be installed on each of the drive(or computer). Hence the need for 5 licenses.
Jack Bauer: Thank you for clarication. All questions are answered.
Mohamed Ameen: You are welcome.
Mohamed Ameen: Thank you for contacting Acronis Customer Central. Have a great day!
