iTunes install error

Hi,

I downloaded the latest iTunes installer, which obviously comes with all the
QuickTime stuff I will never use. Unfortunately, after having copied all the
iTunes files the installer try to install the latest QuickTime package and
the installation fails *systematically* :

---------------------------
iTunes - InstallShield Wizard
---------------------------
QuickTime installation failed:

Error Code : -3
---------------------------
OK
---------------------------

After having displayed this dialog box the installation is halted and when I
try to run iTunes I get the following error :

---------------------------
iTunes
---------------------------
iTunes cannot run because some of its required files are missing. Please
reinstall iTunes.
---------------------------
OK
---------------------------

I tried to uninstall/reinstall iTunes but nothing changed.

Did someone experience the same problem ? What can I do in order to run this
f*** iTunes ?... It's driving me nuts !!

Best regards,

A.R.
