No, that's not working either. I tried:

cmd "C:\PRogram Files\Some Company\Some Product\Prog.exe"

and it doesn't work, even at the command line, even though

"C:\PRogram Files\Some Company\Some Product\Prog.exe"

typed by itself at the command line fires it right up.

BTW, cmd.exe by itself gives me:

Microsoft Windows 2000 [Version 5.00.2195]
(C) Copyright 1985-2000 Microsoft Corportation

at the command line.

system("cmd "+cmd)

doesn't work either.

For crying out loud this was working fine until today!

FindTest.executable?(cmd) still says TRUE, so does test(?e,cmd).

I'm not sure why the difference between yesterday and today (but you are 
working with Windows, remember ;-).  But I believe your problem is that 
you need to run your executable with command.com (on win95|98|ME) or 
cmd.exe (on winNT|2K|XP).

So you need to do:

cmd = "C:\\Program Files\\Some Company\\Some Program\\Prog.exe"
system("cmd.exe "+cmd) #NT|2K|XP

and

system("command.com "+cmd) #95|98|ME

apparently things like 'echo' and 'cl' are built-in to the command 
interpreter, so you don't need to add the extra bits to get them to work.

Or you could use Win32::TimedSystemCommand or 
Win32::Process from my Win32 module.
