Itanium-based 64-bit drivers are not compatible with x64-based versions of Windows because they are compiled specifically for the Itanium operating system. Drivers that are written for Itanium-based computers will not install correctly on x64-based versions of Windows.
To obtain device drivers that are not included on the installation CD for x64-based versions of Windows, use these methods in the following order:
- Method 1 On the Microsoft Windows Update Web site, search for a driver that is certified by the Windows Hardware Quality Labs (WHQL). To search for a WHQL-certified driver, click Start, click Windows Update, and then follow the instructions on the Windows Update Web site. Alternatively, you can visit the following Microsoft Web site:
- Method 2
Obtain a WHQL-certified driver from the device manufacturer's Web site. For information about how to search for a WHQL-certified driver on the device manufacturer's Web site, contact your device manufacturer.
- Method 3Obtain a beta or non-WHQL-certified driver from the device manufacturer.
Important We do not recommend drivers that are not WHQL-certified. Microsoft cannot guarantee the compatibility of device drivers that are not WHQL-certified.
Note It is the responsibility of the specific hardware or software vendor to make sure that programs and device drivers are compatible with x64-based versions of Windows.
For information about your hardware manufacturer, visit the following Web site:Important The driver and the driver Setup program must be 64-bit compatible.
