Facebook FQL get list of users and include installed parameter

I would like to get a list of friends of a user. In this list I would like to know which users also have the app installed.

According to https://developers.facebook.com/docs/reference/api/user/ there is an installed parameter that can be accessed through the graph api.

I am trying to do so with the following query but I am having trouble getting the result. (I split the query on multiple lines for readabilty)

var query = "SELECT uid, name, first_name, last_name, pic_square, status, installed  FROM user ";
query +=  "where uid IN (SELECT uid2 FROM friend WHERE uid1 = " + Titanium.Facebook.uid + ")";
query += "order by first_name";


Just had a look at this using the api explorer. You want "is_app_user" as the field for an FQL query and not installed as that doesn't exist in fql but is an api endpoint

fql?q=SELECT uid, name, first_name, last_name, pic_square, status, is_app_user FROM user where uid IN (SELECT uid2 FROM friend WHERE uid1 = me()

or try
