Endpoint security improvement
EMS 6.4.7 adds an improvement to endpoint security that impacts compatibility between FortiClient and EMS and the recommended upgrade path. The FortiClient 6.4.7 installer is not available on FortiGuard Distribution Servers (FDS). To install the FortiClient 6.4.7 installer, you must download it from Customer Service & Support. See Endpoint security improvement.
If the EMS server certificate is invalid, and FortiClient is upgraded to 6.4.7, by default, FortiClient displays a warning message on the GUI when trying to connect to the EMS. The end user should click allow to complete the connection. FortiClient does not connect to the EMS if the end user selects deny. If the end user selects deny, FortiClient retries connecting to the EMS after a system reboot. The same warning message displays while trying to connect to the EMS. The end user should click allow to complete the connection.
FortiClient EMS Microsoft Visual C++ installation
The EMS installation includes installation of Microsoft Visual C++ (VC) 2015. If the server already has a newer version of VC installed, the installation fails. See VC++ 2015 Redistributable installation returns error 1638 when newer version already installed.
If you have a version of VC installed on your server that is newer than 2015, uninstall VC before installing EMS.
SQL Server Enterprise with 5000 or more endpoints
When managing more than 5000 endpoints, install SQL Server Standard or Enterprise instead of SQL Server Express, which the EMS installation also installs by default. Otherwise, you may experience database deadlocks. The minimum SQL Server version that FortiClient EMS supports is 2017. See the FortiClient EMS Administration Guide.
Split tunnel
A split tunnel configuration that functioned in FortiClient (Windows) 6.4.1 no longer works after upgrading to 6.4.7, unless you have configured a per-tunnel configuration in EMS.
