Why the author didn't specify that VN can be installed only on PCEM with Windows 98 installed and only if you rewrite Setup.INI with correct settings.
And after that you need to copy everything from PCEM hard disk and only then it will work on Windows 10.
And this operation should be repeated 5 times because there are 5 disks.
It is not recommended to install this VN (and a number of others of the same developer) on the operating system you are using now or you can damage your operating system because the installer in the operating system VN replaces, and the installer is 16 bit.
When will the author learn how to run VN before publishing?
