Issues in seting up iTunes - error GEAR drive

Hello,


I have windows vista installed. And I have been trying to install i tunes. Every time I run the set up it gives the following error : 'Unable to install the GEAR driver set at this time. The GEARAspiWDM service used by the GEAR driver set is scheduled to be deleted during the next system reboot. Please reboot the system and run iTunes again.' . However after rebooting the system, when I run the set up it shows the same error. Please help.
