I've only ever installed in on my desktop PC.
But I'm finding I would like to use it occasionally on my laptop.
I know some software from some companies can be used on 2 or 3 maachines.
Can I legally install Sonar on another PC.

you can legally install sonar on up to 2 pc pre the ULA agreement.

Thanks.
I know it used to be just 1 PC.
2 PC's is fine for me.

this is about as recent as it it gets ;-)

EDIT: there used to / I believe there still is...a rule where you can only use it on 1 pc at a time.
meaning, you may have it installed on 2 pc's, but only use it on 1.
 
For Example: don't let your brother use one of your copy's on your laptop in the dining room, while your using another copy on a desktop in the kitchen.
 
so you can only "Use" 1 copy at a time, but may install it on 2.
 
good luck my man !
