When starting the Arbitragewin for the first time you will be asked for your license key.

• Please enter your email and license key if you already bought the license key. If you don't, click Close button and Arbitragewin will run in Demo mode
• If you do have your license key with you, please read Term and Condition carefully. If you agree with it, please check “I Agree” and proceed.

Single license for one single machine. However, if you want to use the same license in another machine, you still can migrate the key by clicking “Transfer Key From Other Machine” By doing this, your Arbitragewin in old machine will no longer work.
