 * [@michaelnorth](https://wordpress.org/support/users/michaelnorth/),
 * This is a known issue. Basically WordPress uses two different libraries. The 
   first is ZipArchive which is a PHP module and is not necessarily activated on
   every server. This library handles updating correctly.
 * If ZipArchive is not activated, which I think is the case with your setup, WordPress
   uses PCLZIP to unzip the downloaded plugin zip. It seems this library has difficulty
   with nested zips which is the case with the plugin since we include zip skins.
   We’re currently trying to develop a workaround.
 * In the meantime, unzipping and then FTPing it up to your server should act as
   a workaround.
 * Thanks.

 * Understood, thanks. One more question please . . .
 * Is this WP plugin equivalent to the version at [http://www.longtailvideo.com/players](http://www.longtailvideo.com/players)?
   In other words, is the WP plugin current with the standard download, or is it
   an earlier version of the JW player? I just want to understand if I’m getting
   all the features of the standard download in this plugin. Thanks.

 * The WordPress plugin makes use of the most recent version of the JW Player.
