i have tried using Virtual Pc with a clean xp sp2 using wmp10, i applied windows installer 3.1 upgrade (necessary to setup zune 2.5 and with windows update disabled) and used the zune 2.5 setup from the net. then i disconnected the internet and tried to install zune 2.5 and a message appeared saying "an internet connection is required to complete setup"... then i connected to the internet and the setup program downloaded some updates from the net and installed, then checked and got a non-working mirakagi...
it seems M$ is winning
