I'm trying to run a program with command line parameters put together by node red. When executed from node red I always get "File Not Found" (exit code 4) but if I run the exact same command from cmd.exe it works (exit code 0). What are the differences in the environment between the two? [image] T…

HOLY CRAP I GOT IT! So after changing my windows encoding to use Beta UTF-8, it still didn't work, but poking around the nodes a bit I noticed that the "hyphen" for the -r option was PHYSICALLY LONGER than the hyphen used for the -p option. My assumption is that it was then ignoring the -r and thu…

on windows you may need to use double \\ to escape the \ or use / instead.

I've tried with and without the escaping but the result is the same. It's not having any issues running the binary AFAICT. From the output it's auto-adding proper escaping. Input to the exec node: {"topic":"","ip":"::ffff:10.255.242.149","port":53619,"_session":{"type":"tcp","id":"a883dca.881792"}…

[image] hobbes1069: What are the differences in the environment between the two? I think that's the key here. You're probably in different accounts and have different privileges/access.

I'm somewhat new to running NodeRED on Windows but I don't think it's login related. I did a default install of NodeRED as a normal user so it's installed in my home directory and I'm running cmd.exe as the same user which is why I suspect an environment difference. That being said in talking to th…

Try putting the command into the msg.arguments and remove it from the exec node so msg.argument will contain the full command and arguments. And try it with the forward slash

I tried the first part with the same result. I'm not sure what you mean by forward slash.

Can you try a simple exec of "dir n:" then "dir N:/DNCMax8" to check it can read that path

I tried forward slashes with the same result. I also created a test exec node to list the directory and it succeeded. [image]

[image] hobbes1069: DNCMaxCtrl.exe IS being run, but terminating with exit code 4, which means the program I am requesting is not found, What is this program that is not found? Does finding it involve finding a file? If so then how does the exe know where to find it?

Different results running command manually or in exec node

The "File not found" is a message I have constructed based off the exit code of the binary. DNCMaxCtrl.exe IS being run, but terminating with exit code 4, which means the program I am requesting is not found, but the process succeeds when run manually with the exact same command line options.

Maybe I should post a snapshot of the whole flow when I'm in front of my work computer.
