I recently decided to use the HBB. So I downloaded the program and placed it in my apps folder on my SD card. I was looking at the different games and apps on the HBB, and when I click on one, it asks to install. I got nervous and cancelled the install. Why is it necessary to install the game and does it install it permanatly on my Wii? Do I have to install every time I want to play the game or app?
