Here are the steps to do so:

1) You need to use this step by step guide to connect user to your facebook page in order to fetch user basic information

FB.api('/me', function(response) {
    console.log('Good to see you, ' + response.name + '.');
}

2) After knowing that user is connected using facebook you need to issue the graph GET request to find out about this user that he liked your page or not

FB.api('/me/likes/YOUR_APP_ID', function(response) {
    console.log(response.data);
}

3) And then run your business logic (whether to take user to download page or other page)
