Keep in mind it was 11 and a half years ago that this conversion was created and posted so I do not remember it too well. What I can say is 'Skeraxe' was and probably still is a very good coder and Installer Creator. I have met him personally and he is a very honest and trustworthy guy.
The Custom Installer was created using Visual Basic 6, the 3 files are Visual Basic files, from memory they are needed for the Installer to work and need to be included on the DVD.
I dont remember having issues with the files, if I did I would have mentioned them in my post.
I burn all games using a cut down version of Nero, I've never had a problem with 'hidden' files not copying over. I use 'UltraISO' to edit ISO files.
I would do what Pakrat has suggested and 'change all attributes, remove read-only & hidden'. This 'should' work.
The only other thing I vaguely remember about this game is 'at the time' it could only be installed by using a Custom made Installer.
Good luck and hopefully you get it sorted.
EDIT: I have located my Converted DVD for this game, Yes I have the 3 files on my DVD and the Properties Attributes are still marked as 'Hidden' and 'Read Only' on the DVD.
