Re: an exe can be executed from cmd but wraping into perl fail to run

To see if your command is failing or exiting with a nonzero code, which usually indicates an error, try inspecting $? and $!. Or, even better, use IPC::System::Simple's capture, since that does the interpretation of $? for you.

$? prints 0 and $! prints nothing.	[reply]

That's strange, but we'll need more information to help debug. Please provide code, sample output, anything else you can think of, see also How do I post a question effectively? Did you try the suggestion of using `capture` from IPC::System::Simple? Also, try using `capture` from Capture::Tiny, because that also captures `STDERR`.	[reply] [d/l] [select]

It is on windows system and the perl i am using comes from Application vendor (HP). i can not add additional module in it. I will raise support case with vendor itself then. Thank You for your response. -KAKA-	[reply]
