Here is a quick tip if you encounter this error while installing WordPress plugin on upgrading plugins from WordPress admin interface.
We across this nasty error while working on a Windows hosting with Plesk interface.
Error: Download failed. Could not create Temporary file
I had given recursive 777 permissions to wp-content before this and still got the error.
The easy fix was to change the WP_TEMP_DIR setting in wp-config.php from
define(‘WP_TEMP_DIR’,ABSPATH.’wp-content/tmp/’);
to
define(‘WP_TEMP_DIR’,ABSPATH.’wp-content/uploads/’);
