Man, I don't know. If calc and notepad work, the agent is working, so that's a start. What exactly do you have in your command field? If you type that same thing in your cmd prompt while you're in a different folder, does it run the batch file? I ask just to verify that the folder is in the PATH..
It might be that batch file is expecting you to be in the folder where the batch file is, so you could add a command to your batch file to cd to that folder.
EDIT: Ron and I figured this out. It turned out he needed to close and open the TRIGGERcmd agent (or just reboot) after he added the batch file's folder to his PATH.
Ron also explained how ahcmd works. It can send commands to X10 devices. It's a simpler way to do it than @Nate-Hales (aka Bubba's) method that uses the curl command. The ahcmd.exe tool comes with this installer: http://voxcommando.com/files/ahsdk_install.exe
FYI, Ron's command to turn on a lamp via X10 was:
ahcmd sendrf e1 onSo with SmartThings, he could turn on parameters and make the command:
ahcmd sendrf e1And SmartThings would add the on or off part of the command.
