I just upgraded to Parallels Desktop 6 (from 5), but have no network connectivity because no network adapters were installed along with Win7 Pro 64 bit (upgraded from XP). I tried scanning for hardware changes in the device manager as suggested in a related KB entry, but get a "Device driver software was not installed" error from Windows. The results show "No driver found" errors for "PCI Device", "Ethernet Controller", and "Multimedia Audio Controller". This is happening on an i7 iMac running OS X 10.6.4. Any suggestions?
