From Stardock's FAQ's -

Q: I have a laptop and a desktop. Can I install the software on multiple machines?

A: Yes, to a point. Only 1 copy of the product can be used at once per license. But if you want to have it on both home and work or install it on the road that is not only allowed but recommended. As long as only one copy is actively in use (someone sitting at the computer) at any one time, you are covered.

 

Seabass - On a related note, for people running VMs on one piece of hardware, such as a laptop, where only one person is using the laptop at the same time, does one license cover that as well?  I'm thinking about using VMWare sometime next year...

Have I mentioned lately that I love Stardock?  Thanks a lot...

Btw, fwiw take a look at my account and see how much I've bought over the past couple years...if SD continues with this sort of effective licensing (read: it's not a pain in my rear), I'll keep coming back.
