Problem with God of War Ascension.

I have a super slim PS3 with HEN. 100 gb of free space, I tried installing the first part of the game on many unofficial stores such as alex store, black store, darkling store. I also downloaded the game in pkg format and put it on a ntfs usb and opened with multiman, I tried to put the rap file of the game in the folder dev_hdd0/EXDATA. No matter what I try, I always get the error error 80029563. What do I do wrong?
