As to why it's not, given the age and such think over what you did last time and try again. Even think about a wipe and reinstall.
As to that box with a newer version what we often discover is to never fix what's not brought since going back can be impossible because there are such lax controls to roll back.
I have windows 98 and used to use the C-it camera (after using the C-it software package instalation CD-ROM. After not using it for a month I pluged it in and a box came up which said I have a newer version of some file or codec and it recomended I keep it so I clicked YES (to keep the new version)I restarted my computer and the message Class not Registered came up so I uninstalled the C-it software then reinstalled it and I got the message---User buffer not correct for requested application(or something like that. I can't remember the exact words, it flashes off as soon as it appears) I unplugged the camera before reinstalling the CD-ROM as the manual says to do. Dos anyone know what the problem is? Also what does Class not Registered mean? I get that message when I try to watch some video streamers or trailers.Thank you
