Can you run two seperate copies of Live on two machines?

[Citizen]

Is this allowed? Or do you have to purchase multiple licenses?

Also, if I wanted to create a mirror system on my desktop machine and laptop, will 3rd Party plug-in vendors permit that, or do you have to buy second licenses?

These answer your first question:
License policy for Live – Ableton
License FAQ – Ableton

That does not cover third party plug-ins of course. You'll have to checek each and every vendor.

Yes you can, but not at the same time.

Yes you can, but not at the same time.

Ah cool, this is kinda what I thought.

Just to clarify, do you mean that you can have two copies installed – but not running simultaneously?

[[jur]]

Yes Citizen, you can use a single license on 2 different machines, but you're not allowed to run them simultaneously.
