.Net Assembly - Error: Exception: WinSCP.SessionLocalException: Element "cwd" not found in the log f

This is the code I am using. I am able to connect via WinScp GUI using same credentials. I tried by removing/setting log file paths..same error in both cases. Can anyone help me to resolve it.

With sessionOptions
.Protocol = Protocol.Sftp
.HostName = glo.strBBSFTPServerName
.PortNumber = glo.Port
.UserName = glo.SFTPUsername
.Password = glo.SFTPPassword
.SshHostKeyFingerprint = glo.sshKey
End With
With session
.DisableVersionCheck = True
.DebugLogPath = "C:\Development\WinSCPDebugLog.txt"
.SessionLogPath = "C:\Development\WinSCPSessionLog.xml"
'''.XmlLogPath = "C:\Development\Products\MB\MBLogs\MBDataFeedAgent\WinSCPXMLLog.xml"


End With

session.Open(sessionOptions)

Hi All,

This error was due to mismatch in .EXE installed on my server and .Net wrapper referenced in code. Provided Executable path (as Version can changes on server) and now able to connect.

session.ExecutablePath

Thought of sharing it as I have spent lot of time on it.

Thanks
