Need help installing Lexmark X2470 Drivers On My Win7PE

 Hi! Hope someone can help me with this problem.
I have a Lexmark X2500 All in One Printer/Scanner
And the Windows 7 Drivers installation CD that goes
With it. When I try installing the Lexmark drivers on
The Win7PE OS, through the device Manager & I get
Error message then the drivers failed to install. I also
Try installing by using the *.inf drivers file installation
Method, but nothing happens. These drivers installed
Perfectly on Windows 7 but not Win7PE OS. If anyone
Out there has the answers please post here with the
Instructions. Thank's! in advance.
