Marked Birds Database – installation

The Marked Birds Database can be run on Windows and on MacOS.

It was developed in FileMaker Pro 16 but you don’t need to have this installed: the database is delivered as a stand-alone application in a folder containing all necessary files.

For full system requirements, see the FileMaker documentation as well as this statement on FileMaker and macOS 10.14 Mojave compatibility.

Part 1. Updating JAVA

Make sure that the latest version of JAVA is installed on your system by visiting and following the instructions on screen.

Part 2. Installing the database

The database runs from a folder that contains all the files that the database needs.

The installation process involves unzipping the folder from the downloaded file and placing it on your system somewhere.

Step 1. Download the files for Windows or MacOS from the database page.

Step 2. Unzip the file to a location somewhere on your system.

You will end up with a folder named Marked Birds Database v2.x.x (for example Marked Birds Database v2.0.0).

Tip: Create a main folder named MBDB and add the folder to it. Use the main MBDB folder to place any future releases and backups of the database so that you have everything in one place.

Step 3. Open the folder and double-click the file named MBDB v2-x-x.



Tip: create a shortcut to this file and add it to your desktop for easy access.
