If you are upgrading from Version 2/3 you will need a new license key from Crossware.
Please contact our support team at email@example.com for a new license key.
We will need the Company name that bought the Crossware Mail Signature license together with a contact name and email address.
When you install the new Crossware Mail Signature V4 you need to add your new V4 license key along side your V3 and V2 license keys.
Failure to append your V4 license key to your V3/V2 license key could result in existing V3/V2 servers being unable to find a valid license key.
If you will be running a mixed V2/V3/V4 environment, your V2 server MUST be at version 2.931 or above. Failure to ensure your V2 servers are not at this version will result in the server not being able to validate the license when rebooted.
Support for multiple license keys was introduced in V2.931.
If you need to upgrade more than one server, please see upgrading multiple servers
for further information.
