Windows Servers Running IIS
A bug affecting Windows servers running IIS can prevent updating from WordPress 3.5 to WordPress 3.5.1. If you receive the error "Destination directory for file streaming does not exist or is not writable," you have a few options:
- Option 1. Manually install the Hotfix plugin. Please see the Codex instructions for manual plugin installation.
- Option 2. Add the following to your `wp-config.php`. Remove it after updating to WordPress 3.5.
define( 'WP_TEMP_DIR', ABSPATH . 'wp-content/' );
If you need assistance, please try the WordPress Support Forums.
