There are two answers to this question......Can you use 1 license on 2 different machines?

Yes, you can install one licensed copy on two machines
BUT
You can't use them at the same time, as the license is for one user (owner of both machines).
In short, it would not be right to 'go halves' in the same way as you could not go halves on a driving license!!
They wouldn't know. In just the same way as I wouldn't know if someone downloaded one of my pics and claimed it was their own.Does this also apply to the standalone version too, just wondering how they would know you were using both at the same time if the internet was turned off
