## Solution

Certificate Keys should be re-licensed when the IP address has changed and new features or services have been added to your product. When using Central licensing, this should be necessary only when the IP address of the Security Management Server has changed.

You must have "License" or "Administrator" permissions within the User Center to generate a license. Follow these steps if generating a license for the first time or re-licensing a product.

To license a **single** Certificate Key:

1. Log into the User Center at https://usercenter.checkpoint.com/usercenter/index.jsp
2. Click "Assets/Info".
3. Click "Product Center" under "Accounts \& Products" option.
4. Select your account from the "Selected Accounts" menu and click Done.
5. Check the box to the left of the line item that requires a license generation.
6. Click "License" button that has the key icon.
7. Complete all required fields (marked with an asterisk).
8. Click "Activate" button (if re-licensing a product, option will be "Change") .

To license **multiple** Certificate Keys:

1. Log into the User Center at https://usercenter.checkpoint.com/usercenter/index.jsp
2. Click "Assets/Info".
3. Click "Product Center" under "Accounts \& Products" option.
4. Select your account(s) from the "Selected Accounts" menu and click Done.
5. Check the box to the left of the line items that require a license generation.
6. Click "License" button that has the key icon.
7. Complete all required fields (marked with an asterisk).
8. Click "Activate" button (if re-licensing a product, option will be "Change") .

**Note:** You will be prompted to repeat Step 7 and Step 8 for each product you are licensing.

After licensing your product(s), a system generated e-mail will be sent to you. You can also download the license file by clicking on "Get License" button on the License Confirmation screen.
