Fortinet SSL-VPN new command line parameters?

I installed the new version of Fortinet SSL-VPN Client, and upon disconnecting the VPN through RDM, I get the following dialog box:



I see in Task Manager that the command executed through RDM was "FortiSSLVPNclient.exe /disconnect" but should be "FortiSSLVPNclient.exe disconnect" I think.

I don't know if this is a change in RDM or the VPN Client (I installed new versions of both on a new machine, on other machines it works fine though)

Thanks!
