I reinstalled it under C:\ to see if the permissions were also interfering with running the program. I ran the suggested command through command line and it worked. Then ran it through Task Scheduler which also worked. The changes I needed to make were to change the directory the program was installed in and use WinSCP.com as opposed to WinSCP.exe. Thank you for your help in resolving this matter.

You have to specify that you are running WinSCP (the same way you do in Windows Scheduler).
Plus for testing, you better use winscp.com:
"C:\Program Files (x86)\WinSCP\WinSCP.com" /ini=nul /script=FTPVIP.txt /log="C:\WinSCP\WinSCP\winscp.log" /loglevel=0

(Note that I did not ask you to reinstall WinSCP, I've just asked you to point /log to another folder, but OK)

I uninstalled WinSCP and reinstalled it under a folder with full permissions under the C drive as shown by the below path:
C:\WinSCP\WinSCP\

I ran the below command from CMD PRMPT while under the above path where the WinSCP.exe file is:
ini=nul /script=FTPVIP.txt /log="C:\WinSCP\WinSCP\winscp.log" /loglevel=0

I had the below output:
"ini" is not recognized as an internal or external command, operable program or batch file.

During the uninstall could files under the Registry have been effected now allowing the commands to function?

Thanks.

Add arguments:

Start in:
C:\Program Files (x86)\WinSCP\

The local account that runs the task most likely does not have write permissions to the C:\Program Files (x86) folder. Pick another folder, where you know to have write permissions. And try to run the command manually first, it will show you error messages if there's any problem.

I added the /log to the argument but it did not create a log. Could you tell me what I am doing wrong?

I disabled Logging under Preferences (also removed the prior log files from the folder to another location) and then amended the argument a few ways as shown below:

Program/script:
"C:\Program Files (x86)\WinSCP\WinSCP.exe"

Add arguments:
/ini=nul /script=FTPScript.txt /log="C:\Program Files (x86)\WinSCP\winscp.log"
/ini=nul /script=FTPScript.txt /log="C:\Program Files (x86)\WinSCP\winscp.log" /loglevel=0
/ini=nul /script=FTPScript.txt /log=C:\Program Files (x86)\WinSCP\winscp.log
/ini=nul /script=FTPScript.txt /log=C:\Program Files (x86)\WinSCP\winscp.log /loglevel=0

Start in:
C:\Program Files (x86)\WinSCP\

Thanks.

Thank you for the response; I amended the /log onto the Task Scheduler argument. I will send the log after I have a chance to run the Task. Attached I have the a word doc showing the current Preference settings. Also shown below is the FTP commands I have:

I have the below setup for the text file:
open sftp://username:password@ftpsite/ -hostkey="ssh-dss 1024 "key from WinSCP when you copy the script" -rawsettings Proxyport=0
lcd
cd
put -permissions=0777 -filemask="*" -resumesupport=off *
exit

If the /ini=nul isolates the script from the GUI Preferences; what other method can I use and how to run the program automated?

Thanks.

No, as the /ini=nul switch isolates the script from the global configuration.

If I did add it through the argument on Task Scheduler; how would I amend it onto this?

/ini=nul /script=FTPScript.txt

/ini=nul /script=FTPScript.txt /log=c:\path\to\winscp.log

Please post a complete log file!

I would also like to add that I am positive this issue is related to the resume setting. When I use my script to transfer any files under 100 KB then it works just fine. It's only when I upload files over 100 KB that it doesn't finish the transfer and just hangs.
As stated, disabling the feature in the GUI has worked and allows me to upload the file. But when doing it via script, nothing works. I have tried using -resumesupport=off in the put command as well as putting -resumesupport=999999 or any other value of the file size I am trying to send it has the same unsuccessful results. I've also tried using /rawconfig ResumeSupport=off and ResumeSupport=2 when launching WinSCP.com, prior to calling my script. None of that works, either.
When the script runs, prior to the upload, it says "Using configured transfer settings different from factory defaults." which leads me to believe it detects the parameters I'm using, it just doesn't. Unless I am going about it the wrong way but between the documentation and other forums posts, that's what I found.

I apologize for the suggestion. It turns out that did not ultimately fix my problem either. I have tried every variation of ResumeSupport=off and ResumeSupport=2 as well as the -resumesupport flag in the put command. Nothing is working at all, but only from within my script. I am able to transfer the file using the GUI once I disable the resume support. This has been taking up the majority of 2 days and I have made very little progress. I desperately need to find a solution to this problem. I've looked at he logs from my SFTP server and it shows the connection is being terminated by the software. Everything points to this being a problem with WinSCP but I am having trouble finding a solution that works.

Can anyone else help us out?

Thank you for the suggestion of downgrading from 5.11.3 to 5.11.1. It did not solve the problem but felt brought me closer to a solution based on the below output from the logs:

Thoughts?

Thanks.

I have been experiencing the exact same problem recently. We use WinSCP on numerous sites/servers to script file transfers and have never had a problem. After installing the latest version (5.11.3) our scripts that always worked, with the same destination server, started giving us this behavior. We were able to get them to work in the GUI by disabling the resume/multipart options of the settings but were not able to disable it with the script. However, the exact same script worked with no problems when using 5.11.1. Unfortunately, we were forced to downgrade to that version in order to see results.

I know this may not be the soltion you're looking for but it's worked for us after troubleshooting both versions endlessly in many different scenarios and seeing the same, consistent, results.

No, I have the logging set through the Preferences (Normal). Would the logging output be the same with the command line /log as opposed to the Preference-->Logging option?

If I did add it through the argument on Task Scheduler; how would I amend it onto this?

/ini=nul /script=FTPScript.txt

Thanks.

Did you add /log switch to WinSCP command-line in Task Scheduler?
https://winscp.net/eng/docs/commandline#logging

I used a "put" command to transfer all files in the designated folder. The log does not even show a attempt when I run the script. It just lists the files and shows what I posted above and then lists the files again. The commands I use are at the bottom of my original post, none of them seem to be triggered. Could it be because I have the WinSCP program open; it conflicts? Or a Transfer setting needs to be adjusted?

Thanks.

I need a full log file on the script with the get command.
The section "Shown below is the output when script is run:" does not show a script log file. It's GUI log file of "Find Files" command.

Attached is the log requested. I replaced some sensitive info such as Username-FTP Site-IP Address with generic info. Thanks for taking the time to look into this.

Please attach complete log files.
