Well, “legacy” generally means “old” and that implies 32-bit drivers, some of which don’t like working in 64-bit systems. Try using the Win7 32-bit version.
They simply can't. In order for any software to access hardware resources in Windows (and any modern OS at that) it needs kernel drivers. Kernel drivers have to be installed into the OS kernel and must be in the same bitness as the OS. Since Traditional DAQ is 32-bit only it has no kernel drivers that could install into a 64-bit OS. Without kernel drivers, the 32-bit user space libraries simply can't access any hardware. There is no way to get Traditional NI-DAQ to work on 64-bit systems. Period.
The transition to DAQmx was started well before 64-bit systems were available in user systems. But it was designed from ground up to be able to support that and one more reason to go with a completely new driver architecture rather than trying to upgrade the old NI-DAQ with new interfaces. NI-DAQ comes from the beginnings of NI data acquisition hardware, when the underlaying device drivers were actually using a 16-bit segmented memory model and then were upgraded to work with 32-bit Windows 95 and NT. Another upgrade to support 64-bit would not have been a very pretty exercise.
In an ideal world software would be written in such a way that, when a new architecture comes out, you only need to change a compile switch and everything works. In reality that doesn't work that way, not even if you could throw infinite resources into the development of the software. Especially if it needs to work close to the hardware such as what kernel device drivers are specifically required for.
