Both platforms:
• During the installation, the Authorizer application will be installed on your computer.
This application is necessary for handling the Reason authorization (see below) and administration of 
Rack Extension devices.
• At the first program launch, you will also have the option to download additional 
content from the Manage Content window. 
The optional content consists of Rack Extensions and sound banks and is stored in the “Propellerhead 
Content” folder in the “Music” folder on your computer. After the download you will have to restart 
Reason for the optional content to become available.
The Authorization system
Reason uses an authorization system designed to be as flexible as possible, while at the same time 
providing the best possible copy protection for the product. Here's how it works:
• The core of the authorization system is your license number, which is registered to your 
user account on the Reason Studios web site.
• If you have a working Internet connection you can run Reason with Internet Verification.
The program will then contact the Reason Studios web site and verify that Reason is registered to your 
user account.
• If you need to use Reason without Internet access, you can download and install the 
CodeMeter application and then authorize your computer (or Ignition Key hardware) 
from your Reason Studios user page.
During start-up Reason automatically detects that your computer is authorized.
• Finally, if you don’t have a working Internet connection, or any authorized computer or 
Ignition Key hardware, you can run Reason in Demo Mode (the stand-alone Reason ver-
sion only).
This is also the mode you use if you are trying out the program, but haven't yet purchased it. In Demo 
Mode you can work as usual and even save your work. However, you cannot open songs in Demo 
Mode (for details, see “Running Reason in Demo Mode”).
! Note that the same authorization is used both for the stand-alone Reason version and for 
Reason Rack Plugin.
Registering Reason
To be able to run Reason in authorized mode (see “Running Reason with Internet Verification” and 
“Running Reason on an authorized computer - or with an authorized Ignition Key hardware”), the program 
must be registered to your account on the Reason Studios web site.
D If you purchased the boxed version of Reason, follow the instructions printed on the in-
sert.
! If you purchased Reason directly from the Reason Studios web shop, the Reason license 
has already been registered to your user account and you can use Reason by running 
with Internet Verification.
