File ini missing import when run command line

Hi all,

I have problem below:
1. First
I setting tool (WinSCP.exe) and connect server are OK (upload and download are OK).
I have to setting Tunnel public IP (xx.xx.83.85:22, and user/pass authen) and then setting local IP(xxx.xx.247.106:22, user/pass authen) in group session.

2. Second
I switch use command line
ex: WinSCP.com /ini="C:\WinSCP.ini" /script="C:\Program Files (x86)\WinSCP\test.txt" /Log="C:\Log.txt"
Throwing error:

This issue resolved.
My solution:
WinSCP.Com /script="C:\test.txt" /log="C:\Log.txt"

Content of Test.txt:
option transfer automatic
option batch abort
option confirm on

open sftp://user:pass@xxx.xxx.xxx.106 -rawsettings ProxyMethod=0 Tunnel=1 TunnelHostName=xx.xx.xx.85 TunnelPortNumber=xx TunnelUserName=user TunnelPasswordPlain=pass
cd /home/package
put C:\test.png l
close
exit

That's correct. You just do not need the ProxyMethod=0, that's the default.
