Each copy of CrossWorks must be registered and activated before it will build projects or download and debug applications. In this tutorial we are going to request an evaluation activation key and then activate CrossWorks using it.

If you have already activated your copy of CrossWorks then you can skip this page and move on to the next section.

###### Requesting an evaluation activation key

- From the Tools menu, click License Manager.
- If you have a default e-mail client:
  - Click the By Mail button underneath the text "If you wish to evaluate CrossWorks...".
  - Send the e-mail containing the registration key to the e-mail address license@rowley.co.uk.
- If you don't have a default e-mail client:
  - Click the Using Clipboard button underneath the text "If you wish to evaluate CrossWorks...", this will make CrossWorks copy the registration key into the clipboard.
  - Compose a new e-mail addressed to license@rowley.co.uk.
  - Paste the registration key into the body of the e-mail.
  - Send the e-mail.

When we receive your registration key we will send an activation key back to the e-mail's reply address. You use the activation key to unlock and activate CrossWorks.

###### Activating CrossWorks

When you receive your activation key from us, you can activate CrossWorks as follows:

- From the Tools menu, click License Manager.
- Click the Activate Product button.
- Enter the activation key you have received from us.
- Click OK.
- The new activation should now be visible in the Evaluation Licenses folder along with the expiry date, click Close to close the license manager window.

Please note that if you request an activation key outside office hours, there maybe a delay processing the registration. If this is the case, you can continue the tutorial until you reach the Building projects section when you will need to have CrossWorks activated in order to build.
