So before we can do it we need the correct files to install the game. im hosting a few over on packageinstaller.tk but heres how you can get them yourself

1. Switch to the account where the content is available.
2. Download HenKaKu on that memory card.
3. Download The Content
4. Right Before It Finishes Downloading Open HenKaKu and wait for it to say "Downloading complete" This is important the game needs to not be installed just downloaded.
5. Now in HenKaKu once the game has downloaded goto UX0:BGDL/T and there will be a folder named something like 0000001.
you need to copy this entire folder somewhere else.the root of UX0: works fine but u can create a new folder for it if u want
6. Connect Via FTP and take the copy of that folder and put it on your computer.
7. Now Switch Back to the Account you want to put this content on.
8. In HENKAKU Put This Folder that contains the downloaded contents off your computer and back onto your your main memory card anywhere you want.
9. From HENKAKU copy the folder you just put on your vita memory card back into UX0:BGDL/T and delete the copy you had before
10. Reboot your vita and it will start installing.
