I need to send scp as a command through system exec.vi. If I open up command prompt and type scp it works fine. If I hit the windows key and type run then type cmd.exe "/k scp" it works just fine as well When I put cmd.exe "/k scp" in the Command Line input for System Exec.vi it returns 'scp"' is not recognized as an internal or external command,operable program or batch file. Any reason why this is different? I was always under the assumption that if you can type it in Run then it should work just fine in the Command Line input. Thoughts? Thanks,

The path I have scp installed at is "C:\Windows\System32\OpenSSH\scp.exe". I initially noticed that this was part of the system path, but not my user path, so I tried adding it to my user path and restarting LabVIEW. No dice. Using "cmd /c echo %PATH%" did show me a path including the OpenSSH directory though... Setting the working directory to C:\Windows\System32\OpenSSH gave me a new error - 267. Some googling tells me this indicates an invalid directory... peculiar, because it's obviously there. Lots of the links talk about running a process as another user (perhaps LabVIEW is doing something like this?) Copying the scp.exe to my desktop and setting the working directory there produced the expected output for cmd /s /c "scp /?". The /s is presumably doing nothing in this simple case. You said your exe installs to different locations on different computers - does it work with any? Are they all in System32? If they are, I'd strongly suggest checking this: Command Not Recognized When Using System Exec VI (even if not, it's worth a look). This talks about the mapping done by Windows when running a 32-bit process (e.g. LabVIEW 32-bit) on a 64-bit OS with regards to system directories. Following the guidance there, I got the response expected from a working directory of "." and command cmd /c C:\Windows\Sysnative\OpenSSH\scp /?. (but you still need the path).

Hi Jigg,
did you use it for TestStand?
If yes, did you have some trouble with the password?

Oh man that was so long ago I don't even remember what we used it for. My guess is it was straight up LV in that case. Also, I'm not with that company anymore so I can't look at the code.

Sorry!
