Need help about Lovely x Cation Append file.

[Ashley Horizon]

This is the first time I played Hibiki Works title, so I am a little bit confused about append file. I downloaded it and coppied it to the main folder of the game. But when I start the game, the append story is still missing.
I have played the Append life of Hatsukoi 1/1 before. When I open Hatsukoi 1/1 the append story is in there although I didn't finish the game.
Can someone help me with this ? Do I need to finish the the game first and then the append life will unlocked ? 
Thank you in advanced.

I think you have to unlock the append stories first by finishing a heroine route. I you aren't sure, you can also use a 100% CG save and check if the append stories are there.

Fortunately, my own hard copies of Lovely x Cation 1 & 2 had the appends already included, so I didn't have to bother with copying files around and checking if it works.
