Koihime Musou Voice Patch

I just downloaded the game from disc to my Alienware laptop. No issues, installed direct x and checked the compatibility on the disc menu and no issues were shown. Every time when I try to play the game nothing pulls up. I’ve tried setting everything to Japan and nothing will pull up. I’m using windows 11 if that helps. Any help appreciated.

You’re about to dive into an erotic visual novel with point-and-click elements — except the story breaks before you even read the first line of dialogue. You launch the game expecting gorgeous girls and a flood of spicy scenes, but everything immediately falls apart: the interface glitches, the music stutters, and Candy — a character who should be following a fixed script — suddenly speaks directly to you.
Your task is to explore corrupted worlds buried under layers of abandoned source code and meet alluring girls who were never supposed to exist in this game at all. Don’t let them fool you… because beneath all the sex and seduction lies someone’s hidden agenda.
Meanwhile, Candy grows more persistent. She rewrites dialogues, hijacks events, and closes paths as if she’s trying to control every step you take. And the deeper you go, the clearer it becomes: the game isn’t just broken…
…it’s trying to rewrite you.

A couple, Tatsuya Iwase and Kaori Iwase lived in a certain apartment.
One day, the Kayabe couple moved into the next room.
The two are relieved that it they seemed to be a good couple.
But....
They can hear the moans from the other apartment night ...
They didn't notice it until now because it had been vacant, but the walls of the apartment were unexpectedly thin.
The couple are bothered by the lustrous voices that they hear.
In order to put an end to the frustrating days, they decided to talk to the couple next door.
The noise problem that seemed to be solved after that, but then they heard that voice in the daytime ...

This is just out of idle curiosity, but a spoken line in the VN HaremKingdom sounds, almost verbatim, to be the same person speaking the same line in the VN Cafe Stella. I'm trying to look up the voice actor who played the character "Lulu" in HaremKingdom, but can't seem to find the answer.
 
The other character who I think is played by the same voice actor is "Hiuchidani Mei" from Cafe Stella, played by "Neraiuchi Urara" according to vndb.org.

vndb.org does not have an entry for the character Lulu from HaremKingdom (or at least I couldn't find it anyways).

A girl who is active in a band.
Her voice sounds quite youthful, which she feels self-conscious about, so she doesn’t talk much when meeting someone for the first time… or so it seems…?
