Open the BlackBerry World App. Swipe down from the top and go to settings. At the bottom of the screen it shows the version number. Just tap on that and then click "back" to go back to the main screen.
It won't show any messages or say anything happens, but it will basically clear the cache and you will see images start reloading.
It should remove the app from installing and you can try installing again.
