I'm using :

F-Secure SSH Client 5.3 build 23 and F-Secure SSH File Transfer
It works fine when I use the SSH Client. But, when I'm using sftp,
displays :

File transfer server could not be started or it exited unexpectedly.

Exit value 0 was returned. Most likely the sftp-server is not in the
path of
the user on the server-side.

What can be happening ?
