Each Studio One Pro license entitles you to 5 activations on a MAC or PC. This means that you can install S1 on up to 5 systems on a single key.
For customers who have already installed Studio One on one computer and wish to utilize their additional licencees on other computers for studio use or mobile rigs there is no need to use the Studio One Product key again, as it has already been permanently stored in your user account. All that is required to do, is to download the correct installer for computer you wish to install the additional copy of Studio One on and then activate the software on that computer.
Studio One can be installed from either an installation disc or a downloaded installer package, depending on which you purchased. However, due to the nature of software being improved upon and updated as time passes, we highly advise that you do not install the software from the disc (if you’re a customer that purchased a hard copy of Studio One), as CD/DVD's will typically become outdated. For the purposes of this article we will describe how to do this online.

How to identify the bit rate of your Windows operating system:
• Browse to your Control Panel.
• Select "System and Security" and then "system" if you are in the classic view, for the large or small ICONS view, simply choose "system".
• Under "System Type", it will list the operating system bit rate as 32 bit or 64 bit.
Mac OS X Users:
There is one Mac OS X installer for both 32-Bit and 64-Bit. It will be the "Studio One 2 For OSX" link. Open the .dmg file and drag-and-drop the Studio One 2 icon onto the Applications folder to install the Studio One 2 software.
Note: Studio One will run as 32-Bit by default on the Mac.
• To change this, locate the Studio One 2 icon in your Applications folder.
• Right-click or Command-click and choose "Get Info".
• Under “General,” un-check the option to run as 32-Bit. The next time Studio One 2 runs, it will run in 64-Bit mode.
Once the Studio One 2 program is properly installed into the Applications folder of your Mac, you can drag it to your Mac's "Dock" to create an alias (shortcut) to the original program file, which should continue to reside in the Applications folder.
