I think BizTalk requires a specific older version of WinSCP and you can’t just download the latest one.
This error could also occur if you didn’t copy the file to the proper directly.
I found Michael Stephenson’s BizTalk 2016 SFTP blog, and it had a nice PowerShell script.
I just had to
1) Change directory names (I had a Software directory similar to him, but I had to create a WinSCP subdirectory under it)
2) Then PowerShell with the “Run as Admin” option.
Then the script ran fine, I restarted BizTalk Host Instance, and it got past this error, on to other errors that I’ll blog about in the near future.
By the way, I was able to run in a 64-bit host with no problem. I remember that in older version of BizTalk the FTP adapter ran only in 32-bit hosts.
