FCL log file path

Problem

Where do i find Log files of the FortiClient in Windows ?

Solution

You may find some of the Log files directly on the Endpoint,

or you may request the Logs of the Client through FortiEMS.

Logs files may be found directly on the Windows Endpoint here:
C:\Program Files\Fortinet\FortiClient\logs

If you would like to download debug logs from the Endpoint through FortiEMS I’ve already written a guide how to do that:

If you would like to enable debug logs on the FortiClient through the EMS Server this KB might be helpful:
