Solution
The CLI for FortiSSL is not included anymore with the download of FortiClient. You need to download the tools related to the current version of FortiClient here
You need to have a support plan with Fortinet to download the tools. If you don't have a support plan, try to contact Fortinet directly and ask them to send you the file.
The file FortiSSLVPNClient.exe needs to be saved in the installation folder of FortiClient.
