What version of Android is your device running?
I don't know a lot about the Galaxy Tab 4 Nook, but I think the Nooks run a highly-customized version of Android. Does it have the Google Play store, or is it another store you're using to install apps?
What are the symptoms when you try to install? Are you able to find the listing for the app in the store? Does it give you an error message (if so, what does it say)?
