Intel 945GM Graphics Controller drivers won't install on inspiron 6400

Hello,

I have a  Laptop: Inspiron  E1505 (6400)  E1505 , Windows XP Pro SP2, I just reinstalled windows xp and each time I try to install the Intel 945GM Graphics Controller driver from the CD it gives me an error saying:  One or more files that are required for installation are either missing or corrupt.  Setup will exit!

I tried downloading the driver from somewhere else and when I install it it gives me a different error saying:  The computer does not meet the minimum requirements for installing the software!

All other drivers are installed and working fine except the wireless card (which I think is also intel).

I tried installing everything in order like the notebook software and the chipset but I still get the same error.

I would appreciate any help on that.
