"Installing the 32-bit version of iTunes on 64-bit hardware results in the iTunes application not having CD/DVD recording capabilities
*The iTunes installer currently only installs GEAR’s 32-bit driver. In order to gain CD/DVD recording capabilities within iTunes on a 64-bit PC , you must install GEAR’s 64-bit drivers separately from iTunes.*
Because iTunes is not a GEAR Software product, any information listed here regarding using that product is provided as feedback from iTunes users and GEAR Software support engineers. Instructions for enabling CD/DVD recording within iTunes on 64-bit hardware is provided without warranty from GEAR. Installing the 64-bit drivers may involve editing the Windows Registry, and users are advised to proceed with extreme caution.
Install the appropriate 64-bit GEAR driver from the driver updates page
If installing the 64-bit does not provide CD/DVD recording capabilities within iTunes, you may have to manually remove the 32-bit drivers and reinstall the 64-bit drivers"
