Skype Users: If you see phone numbers that look like this or this iinstead of like this you need to temporarily disable Skype's click-to-call functionality during the entire installation process, from start to finish. The easiest way to disable this is to remove or uninstall the "Click to Call with Skype plugin" via Windows' Control Panel's Add/Remove or Uninstall Program function. Skype click-to-call can also be deactivated by disabling the plugin through your browsers' manage add-ons/plugins options (actual procedure varies according the browser type).
