If you can't select your app to create an app install ad in ad creation, check to see if:

• The app is registered with Facebook.
• The account of the person creating the ad has advertiser privileges for the app.
• The ad account is associated with the app.
• You've agreed to the Data Use Terms for App Install ads.
• You've selected an iOS ID or Android key.
• You have a valid URL for either Google Play or the iOS App Store.
• Your app isn't a Page tab app.
• The app is in development mode. You can check to see if your app is in development mode by inserting the app ID into this URL: https://developers.facebook.com/apps/[app ID]/review-status/
