If your hardware device will be installed on both 32-bit platforms and 64-bit platforms, you must provide a native driver package for each platform. You can, however, use a single 32-bit installer to install either driver package. This paper provides information about how to use a 32-bit installation program to install either 32-bit or 64-bit drivers for the Windows family of operating systems.
This information applies for the following operating systems: Windows Server 2008 Windows Vista Windows Server 2003 Windows Server 2003 64-Bit Edition Windows XP Windows XP 64-Bit Edition
For up-to-date information, see “Device Installation Design Guide” in the WDK documentation.
