Yves,
At this time, there are no known issues with running FieldPoint Explorer 4.0.1 with NI-DAQ 6.9.3. You should be able to install those two programs together. You want to be sure that when you are installing that you are only installing FP Explorer and not a newer version DAQ, as the last version of NI-DAQ to support the DAQCard-500 is NI-DAQ 6.9.3. If you continue to experience problems with this, please post a detailed description of the steps that you are taking to install these programs, and describe the difficulties that you are having. Alternatively, you can try installing FieldPoint 3.0.2 if you want to try a different approach to the issue that you are having.
The reason that you are experiencing difficulty with your system is due to the DAQ
Card-500. The DAQCard-500 is one National Instruments' older Data Acquisition Cards, and has been considered a "legacy" board since at least 2001 (the earliest year for which I have a catalog readily available). This DAQCard was replaced by the 'E' Series DAQCards, that offer a number of additional features. Starting with NI-DAQ 7.0 driver support for the DAQCard-500 was no longer included in new versions of NI-DAQ, due to limited usage and demand for these features. You may want to consider upgrading to an 'E' Series Card, which would be fully supported under NI-DAQ 7.x, and would allow you to utilize the new features of NI-DAQmx.
