FileMaker Server uses a license certificate to set the license key. Do not lose this license certificate. Keep a copy of the license certificate in a safe place in case the software ever needs to be reinstalled.
You received an email message with a link to your software download page. Information about your license certificate page is on that page.
The license key ensures adherence to the single user license agreement, which generally allows for use of one (1) copy of the software on a single machine or one instance of a multiple-machine deployment at a time (refer to your Software License). If the license key is invalid or if another copy of the software installed with that same license key is running on the network, the FileMaker Server software displays an error message and does not start.
You can choose to deploy FileMaker Server components across multiple machines that work together to form a single FileMaker Server deployment. You must have a unique license key or obtain a volume license for more than one deployment. You must license one copy of FileMaker Server for each deployment.
To upgrade your license from a trial version of FileMaker Server on the same machine, you must import a replacement license certificate.
To change the FileMaker Server license of an existing deployment, see License settings.
To move your FileMaker Server deployment to a new machine or to upgrade from an earlier version of FileMaker Server, see FileMaker Server Installation and Configuration Guide.
When you import a license certificate, restart FileMaker Server.
