eeupdate utility needed for use in WinPE environment

Hello,

I'm in need of an "eeupdate" utility or equivalent that will work in a Winpe environment. I've attempted to use "eeupdatew64e.exe" but the message I get returned is "Unable to locate the driver component. Please reinstall program".  I'm trying to get this to work in a Windows Deployment Server (WDS) environment so we can modify our MAC Addresses in a script.  Any help would be appreciated.

Thanks.
