Problem getting the sample perl script to run on the apache http server

[Chintan Kachhi <chintankachhi@xxxxxxxxx>]

Title: 500 Internal Server Error

Hello,
I just installed apache http server version 2.2 on my local machine. I copied a sample hello world perl script under the cgi-bin directory of the Apache installation folder and named it first.pl. When I put http://hostname in the web browser url, it shows that the server is installed, since it displays the message, 'It works!'. However when I try to run the script typing the following in the browser: http://hostname/cgi-bin/first.pl , it gives me the error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, admin@hostname and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Looking through the error log, it shows me the following message : [Wed Jul 01 13:33:18 2009] [error] [client 10.184.226.251] (OS 3)The system cannot find the path specified.  : couldn't create child process: 720003: first.pl
[Wed Jul 01 13:33:18 2009] [error] [client 10.184.226.251] (OS 3)The system cannot find the path specified.  : couldn't spawn child process: C:/Apache Software Foundation/Apache2.2/cgi-bin/first.pl

 Is there something that I am missing or doing wrong?
