This software can run inside of Ableton Live - I don't use it anymore, so I'm selling my license and the discs. If you just want the license I can simply transfer it to you and not send the discs. You can then upgrade to the latest version and save some money over buying a new license.

This is how the transfer works. From the Propellerhead website:

To be able to transfer one or several license numbers to another user, you need to know the recipient's user name on the Reason Studios website and also the email address that is registered to that user account.

Once you have these details, log in to your user account and visit the "My Products" page. Check the licenses you want to transfer and hit the "Transfer licenses" button. Please note that you cannot transfer an upgrade license without transferring the license you upgraded from.

On the next page, you'll be asked to fill out the recipient's user name and email address. Unless the details you give us match an account in our data base, you won't get past this step, so you need to make sure you have the correct information.

Once your application has been received, a Reason Studios employee will review the license transfer to make sure everything is as it should be before approving the transfer. Once this is done, the license numbers you wanted to transfer will be registered to the recipients user account. Both you and the recipient will now get an email to let you know that the license transfer has been completed.
