WordPress, IIS 7, 7.5 : Download failed. Destination directory for file streaming does not exist or is not writable

WordPress issue on IIS 7.5

Download failed. Destination directory for file streaming does not exist or is not writable
========================================================================

Add this line of code anywhere in the root file: wp-config.php


/* Setup a temporary folder for uploading and updating */

define( 'WP_TEMP_DIR', ABSPATH . 'wp-content/tmp/') ;

Now create a new folder named “tmp” inside: /wp-content/ and update permissions for IIS users to 'modify' the folder.
