If you elect not to use the Command Center or need to activate SONAR on a computer not connected to the internet follow these instructions.

For now it is WAY easier to use Command center as it keeps track of what you have installed and if that all is the latest version. It also activates your version automatically.
Otherwise you follow scooks link and use the offline activation. I did both just to see and trust me. Install and use Command center it's a much easier ride. .  

I would also recommend using the Command Center for your products. I installed Sonar Platinum on an upgraded system a couple of weeks ago and CC did the job without any problems.

Thanks guys.. the sonar people wont have an issue if i put it on my computer at home ? I already have it on my studio computer..i did buy it outright..is there a max to how many computers to install it to ?

I have had SONAR installed on my studio pc and laptop for years, so no need to worry.

I have it on 7 computers as my back up for the future. I only use 3 of them, the other copies I use to help on the forum and they are "safety" copies. 

Of the software bundled with SONAR only XLN Audio and Celemony restrict the number of active licenses. You may have two active installs each for Addictive Drums 2 and Melodyne Essential. While Cakewalk tracks the number of SONAR activations, they do not impose a limit. Installing and activating SONAR on more than one PC is OK, however; the license restricts use to one PC at a time.

Exactly, Way back Noel or someone said we won't limit your installations but we'll be keeping an eye on this. 
As it is they would have no way to track active and deactivated set ups. I have at least 4 old Daw Hard Drives with complete C drive intact Sonar installed and no long used. Cakewalk would not be aware of those. 
 
And yes, there no way to use more than 2 versions anyways unless like Steve just said, you forgo AD2 and Melodyn. For me this also includes my Air products.
