If you browse to www.farmerswife.com, you can find them in the Help Center section> Installers.
PUBLIC INSTALLERS:
Public Installers folder contains installers for the latest releases of each version: 6.1 SP1, 6.2 SP2, 6.3 SP1, 6.4 SP2, 6.5 and recently added 6.6 and 6.6 SP1.
All previous releases are available in the Previous Releases Folder.
Once you open selected folder you can see Server and Client installers for Windows, Mac or Linux.
In 6.6 Service Pack 1 folder we have added sub-folders to point you to the correct installers depending on the operating system of the machine, where farmerswife server or client app are installed.
If you are below Mojave, you should choose Alternative Installers Folder.
To connect to the Server you need to download Client installer and follow the installation instruction for Windows, Mac or Linux.
PREVIEW & BETA INSTALLERS:
Preview and Beta Installers should only be used under certain circumstances.
If this happens you will receive access to Preview and Beta installers together with detailed instructions on which version to use and how to upgrade to it.
