Plugin Updates
If you are installing the plugins for the first time, just upload the contents of the extracted zip file to your forum folder, Log in to the forum as an Administrator and navigate to Admin | Other | Tools and perform an application reset. The plugins should install themselves.
If you already have the plugins installed, remove the 
App_Data folder from the extracted folders before uploading to your web server
