SSH.NET loading error

[aspfun]

I followed the link to create a sftp client.

https://www.codeproject.com/Tips/111...-in-Visual-Stu

It works fine in my local pc and exe file sftp.exe was copied to a file server.
But user got an error once ran copy of sftp.exe file from file server.
This is error.

Could not load file or assembly "Renci.sshnet, ..."

Company block reply feature. I have to reply here

Thank you for help.
I checked my application and found that dll files are in different folders.
Some are in ./bin/debug/ folder and others are in ./package/ folder.
When I copied sftp.exe to a folder mysftp, should I copy all dll files into mysftp folder of file server?
Or, I have to create bin/defug and package folder under mysftp folder?
