I'm trying upgrade my Acer Aspire E380 from Vista 32 bit to Windows 7 Professional 64 bit and getting an error that no device drivers were found. This happens after booting from the Windows 7 DVD.  The Acer support site only provides Vista 32 bit drivers for this machine.  Where can I find the drivers needed for Windows 7 Professional 64 bit?
