Hi I've spent a good few hours trying both yours and Cyclops' mods, but vista fails to activate and both mods start in reduced functionality mode (with internet connected). The BIOS appears stable. Will it make difference if I reinstall Vista from scratch and then run the Asus licenece again? At present I'm just updating the BIOS on a fully functioning Vista operating system, which has successfully activated with the V1.4 mod. Thanks for all your help Evan
