Save your energy and frustration trying to install 32 bit drivers on a 64 bit operating system. You may want to peruse this article from Microsoft:
http://windows.microsoft.com/en-us/windows7/understanding-hardware-and-software-for-64-bit-windows
particularly the statement:
"A computer running a 64-bit version of Windows needs a 64-bit driver for every piece of hardware installed in it or connected to it. For example, if you're trying to install a video card (graphics card), printer, or other device that only has 32-bit drivers available, it won't install on a 64-bit version of Windows."
In other words, the bit depth of the driver must match the bit depth of the operating system or it will not install, and "Compatibility Mode" applies to programs, not drivers. Many of us learned this the hard way some years ago with the advent of Vista-64, when our favorite old hardware would no longer work. Sadly, Vista, itself, took the bad rap, but the problem was not Vista, but the 64 bit driver requirements. Those who migrated from XP to Vista-32 did not experience those problems. The 32/32 and 64/64 driver requirement match have carried over into Win-7 and Win-8. There are those who believe that they have installed 32 bit drivers on 64 bit Windows, but what they have actually encountered is a dual mode installer which automatically detects the type of operating system and installs the appropriate driver(s).
When I migrated from a Vista-32 desktop to a Vista-64 machine, I immediately lost USB-MIDI communications with my Casio WK-3800, because Casio refused to write a 64 bit driver for it. I found a work around by kludging a 64 bit Edirol sound module driver to work with it, but several years later, when Casio released its 64 bit Win-7 driver, the WK-3800 worked fine with it on Vista-64, even though Casio still does not recognize it. This indicates that it is not so much the version of Windows, but rather, the type (32/64) of driver that makes the difference. It also shows Casio's continuing lack of understanding about Vista-64.
As a side note, old 16 bit Windows 3.X programs will not install/run on 64 bit systems - not even in Compatibility Mode. There isn't even a Compatibility Mode choice for them. The real foolers here are the programs that touted being Win-95 and Win-98 compatible, when they were just old 16 bit Win 3.X programs that would run on those operating systems (as wells as on 32 bit XP and Vista), but not on the 64 bit systems.

Exactly my point ! Here we are three years later, and we are still having these 32 versus 64 bit discussions, so there is apparently still a lot of misinformation about this topic. In a way, I am glad that keyboard-all drug it back into the limelight.
