On 64-bit Windows operating systems, you can execute both 32- and 64-bit applications. However, 64-bit applications must use 64-bit drivers, and 32-bit applications must use 32-bit drivers. Make sure that you use a driver whose bitness matches the bitness of the client application:
.msifor 32-bit applications
.msifor 64-bit applications
You can install both versions of the driver on the same machine.
