Upgrading FileMaker Server on an existing single machine (Windows and macOS)
Starting with FileMaker Server 19.1.2, you can install FileMaker Server without first uninstalling the previous version. If running an older version, follow the NEW installation instructions: Click Here
Follow your electronic download instructions to download the installation disk image and license certificate file. Place the license certificate in one of the following locations:
the default Downloads folder
the installer folder (the folder where the installer is located)
the License file folder
Windows: [drive]:\Program Files\FileMaker\FileMaker Server\CStore\LicenseFile, where [drive] is the drive on which FileMaker Server is being installed
macOS: /Library/FileMaker Server/CStore/LicenseFile on the machine where FileMaker Server is being installed
Start the installation.
Windows: Double-click Setup.exe. If a User Account Control alert appears, click Yes.
macOS: Double-click the installation icon. If a security message appears, click Continue.
Windows: Choose a language, click OK.
Windows: If your existing FileMaker Server still running, you are prompted to allow the FileMaker Server installer to stop it. macOS : see command line at bottom to complete stopping of services.
To continue with installation, click Next (Windows) or Continue (macOS).
Read the important information displayed. If there is a task you did not do, quit the installer and do the task.
Review and accept the end user license agreement.
Choose an option for the FileMaker Server user account (the account under which the previous version of FileMaker Server was running).
To use the default account, choose Local System (Windows) or fmserver (macOS).
To use an existing account on this machine, choose User Name, enter the account's user name and password. You may want to choose this option if you already have an account that has privileges set as you want—for example, to access network-attached storage.
If the existing user account you specified does not have sufficient privileges for FileMaker Server to run, the installer displays an error message. See Installation notes.
Enter your macOS user name and password, then click Install Software.
