cant install vista business

after the vista install routine finishes copying the files from the cd and begins the installation it fails to read the hard drive. the error is

'Windows cannot access the required file
c:\$windows.~LS\sources\6acfee.....\install.swm
Make sure all files required for installation are available, and restart the installation.
Error code 0x80070490'

Thats it

have xppro running fine. This is not an upgrade.

any ideas

 

It may be having a hard time reading your install CD.
