Won't install

[tada1]

I purchased Karaoke suite 4 on diskette 7/19. Microstudio and Keyrite will not install from the disk. Vogone and Khp installed satisfactorily. When trying to install Microstudio the following error msg pops up; An error(-5009:0x80040702)has occured while running set up. Keyrite responds with: the disk is corrupted please obtain another copy. I am running windows XP on a new Dell P4 system. My assumption is that I have a bad disk but in reviewing the FAQ's, problems with installation of Microstudio from diskette seems to be fairly common. I've tried everything including powering down.

Thanks,
Terry
