How to install, play and use AGTH and other traslator out there with Angel's Feather?

Hello, so I really want to play the Angel's Feather game because I watched the OVA and thought too bad it ended there. Okay, so I have the file to mount, I can mount it. I have Windows 7. I have the DVD ver., the Kohaku no Hitomi for the 18+ voice added, the AF 18+ disk, full CG save, and the no DVD patch. Yeah, I hoarded cause seriously I don't know what to do. I also have AGTH, Atlas, ITH, and TA. I've been trying to install and play it using these translators but I dont know what went wrong with the hooks of the translator. I've been so confused on what to do, because there are many websites with many suggestions or guides on how to do it, but I just can't make it work. So please. Is there anyone there with the knowledge to help me with the things I have on my laptop? Or even suggestions on what more do I need to make it work.
