Answer 1

There are a few things to check:

• File permissions. Set them to 0777 temporarily to see if it's working
• Maybe the exec function is blocked. Check php.ini (or phpinfo() ) for disabled_functions
• Third options - is one you really always need to consider - an error in your script.

Happy debugging !

Answer 2

PHP/IIS will need to read/execute permissions to the command you are trying to execute with your exec() function.

Go through PHP documentation for exec() function article.

Hope, It will resolve your problem.
