I recently had to format my hard drive and reinstall windows. i installed windows 7 home premium 64bit, because that was what was originally on the system. i downloaded the correct network drivers on a different computer, placed them on a usb flash drive, then attempted to install them on the x1470, however im getting an error that says the drivers i am trying to install are for the incorrect version of windows, so i went back, downloaded all of the drivers for both the 32 bit and 64 bit systems and tried to install them all one by one. i got the exact same error for every single one. the system is either 32 or 64 bit, so why does it tell me i have the incorrect version no matter which one i try install?
