I can download the app but when I try to install it gives me an error that I can only install it through "windows store" but when i go to the windows store, I can't seach or find the oovoo app anywhere! i am very new to this so I don't even know if its possible to install it. Please any help is greatly appreciated. Thank you so much in advance
