Solution
The PCI/PXI-5102 digitizer is not supported on any 64-bit operating systems, i.e. it is not supported on Windows 7/8.1/10 64-bit. However, it is supported on 32-bit versions of these operating systems.
The PCI/PXI-5102 are supported and can be programmed using NI-SCOPE driver. At low-level, for these devices, the driver is dependent on legacy NI-DAQ (Traditional DAQ driver), which is no longer maintained by NI and doesn't offer 64-bit support.
If you are required to use Windows 7/8.1/10 64-bit, then you will need to upgrade your hardware and adopt newer digitizers/oscilloscopes: in this case, NI-SCOPE driver is relying on the NI-DAQmx driver, which provides 64-bit operating system support. You can refer to
