Hello,

Com object is initialized, but cannot find Open method

What's may be wrong?

P.S. that happens only in a server mode(executing behalf on certain service)

Client mode is ok.

Thank you in advance.

PS: Debug log is below

Thanks for the log. Can you also include a log from a client mode and your code?

I'm also sending you a custom build for testing. Please try it (and include its log too).

Hello, Martin. Thanks for the letter. Will install it a bit later. Before it here is the code:

Code:
Try
       
        sessionOptions = New COMobject("WinSCP.SessionOptions");
        sessionOptions.HostName = "XXX";
        sessionOptions.UserName = "XXX";
        sessionOptions.Password = "XXX";
        sessionOptions.SshHostKeyFingerprint = "XXX";
       
       
        session = New COMobject("WinSCP.Session");
      //session.SessionLogPath = "D:\log.txt";
      session.DebugLogPath = "D:\log2.txt";

        // Connect
        session.Open(sessionOptions);
      session.Dispose();
      Message("ОК");
    Except
      Message(ErrorDescription());
    EndTry;


And client log(but old version):
