Can't create file 'c:\WINDOWS\system32\null Windows 10

Can't create file 'c:\WINDOWS\system32\null Windows 10
System Error. Code: 5.
Access is denied

I have everything working on a Windows 10 Pro machine, and this is a Windows 10 Home installation. I am running a script that ran on my other machine after creating a key and using all the same folder and txt file.

This occurs at the Key Request below is the script resulting

In scripting, you should use a -hostkey switch to configure the expected host key.
(Y)es, (N)o, C(a)ncel (9 s), (C)opy Key, (P)aste key: No
Can't create file 'C:\WINDOWS\system32\null'.
System Error.  Code: 5.
Access is denied
Authentication failed.
Unknown command '@copy'.
Unknown command '@copy'.
No session.

Everything seems to work on the GUI version, but it does not copy the file to my Windows box from the SFTP server.

Thanks.
Best Regards,

Carl

The GUI Version does copy the file to my directory.

I guess that your immediate problem is that you have used /ini=null instead of /ini=nul.
But it also seems that you have several other problems.
See https://winscp.net/eng/docs/scripting#hostkey
If you need further help, please attach a full session log file.

To generate the session log file, use /log=C:\path\to\winscp.log command-line argument. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Martin,

I appreciate your response and will read through your suggestions. I have one machine working perfectly, and I copied the script on the new machine, I also got the hostkey, so I am really doubting this will help. The first machine worked without the hostkey.

The log file should be helpful and I will read through everything again.
/log=C:\path\to\winscp.log.

Martin,

This product does work on Windows 10 Home, right? If so.

Here is the end of my log. You commented about a .ini file. I have not modified one, and have not seen one.
