Rome: Total War not installing

[Dismounted Ritterbrüder]

Hello all. I've had RTW gold edition (which has original game + BI) for years now and I decided to try and install it, as my interest in it was rejuvenated. It is in very good condition, almost everything in the box is still in it and mint, and the discs have little to no scratches on them. I insert disc 1, it installs, everything is well and good. Then it tells me to insert disc 2. So I do. I click 'ok' but the message pops up again. No matter how many times I click ok or how many times i enter disc 2, it still tells me to insert disc 2. Does anyone know why this might be, and, if possible, how to fix it? Thanks.

If vista or Win 7, disable the UAC.

i tried that and it still tells me to insert disc 2... when i put it in autoplay asks me what to do, the only option is to look at the folders on the disc, i usually just exit out of that and it still says to insert disc 2

EDIT: So I looked at the files on the disk with autoplay and it says the only thing on the disc is a winrar archive called data3.cab, when I try to view it it says the file is in an unknown format or damaged
