So it's the same problem that Come See Me Tonight had sorta, i basically just copied all the files off of the disc to a location where i want the game to go then i made a registry.reg file with this in it to add info to the registry.
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\ZyX\HYOUIUS]
"VideoDir"=".\\"
"InstallType"=dword:00000004
"SaveDir"=".\\"
"DataDir"=".\\"
"MusicDir"=".\\"
"VoiceDir"=".\\"
“WndPos”=hex:7e,02,00,00,5e,01,00,00
“UserSetup”=hex:01,02,01,01,01,80,80,80,03,01
Then put the crack into the folder.
I am not sure all of it is necessary but i had the same problem with Come See Me Tonight and the solution someone put up was something like this, i actually looked to another site which had the copy solution rather then installing it but that still gives you the registry error, but a guy there gave a registry solution where you had to put the location of the game into the reg file to get it to work which didn't work for me so i copied what the Come See Me Tonight solution had, either way i managed to get it running.
I wouldn't mind knowing if this works for people, i must admit this is my first time giving out advice here about a possible fix.
EDIT
I swear this game wants to scare me with problems at first there was no audio but it turns out that all the audio was set to off, you also need to have bgm up for voices to appear but you don't need it set to on, then only the text of the main character was turning up but in properties i had to set message mode to text+voice for whatever reason i don't think either of them were set.
