According to License: How many computers can I install/run Vegas Pro 9 on?
 

Hey, does anyone know how many computers can I legally install Vegas Pro 9 on?

and if more than one - can they be run simultaneously?

Googling the subject I ran into some posts by people mentioning that the license of Vegas 8 allowed installing 2 (some mentioned 3) computers with the same copy.

If anyone has more specific information and regarding specifically Vegas 9, I'd really like to know.

Thanks! :)

I believe it's three, but you can only run one at a time.

Thanks Zulqar,
I've been getting the notion it's more or less how you say...

2-3 computers...

some say simultaneous use is okay.

som say not.

I've searched for Sony's official documentation on this, but can't find it.

I really need a definitive answer cuz the difference between one answer and the other can mean being legal, or not.

Here's the definitive answer.

Installing or registering software on multiple computers

Question

What is the policy for installing and registering a Sony Creative Software program on multiple computers?

Answer

According the Sony Creative Software End User License Agreement, there is no restriction for installing or re-installing the software on multiple computers. Many users need to have the software installed on more than one computer (i.e., a home PC, a work PC, and a portable laptop) for the convenience of being able to work on projects at different locations. Our EULA allows for this type of use and only the purchase of a single license is required to do so.

If multiple, simultaneous use is needed, then according to the EULA purchase of multiple licenses will be required (i.e., a classroom or a business with multiple people using the same program at one time).

* Each time the software is installed, it may be installed using the installation disc or by downloading directly from our Updates page.
* Reinstalling requires that you enter the serial number provided with your ordered materials.
* There is no need to de-activate or de-authorize your software when you are installing on a new computer.
* The software should be registered using the same contact and user information each time it is registered.
* For information regarding purchasing an ACADEMIC multiple user site license, please contact one of our Academic Resellers.
* For information regarding purchasing a COMMERCIAL multiple user site license, please contact our Customer Service team.

Perfect!
Thanks Mike.
