cdaq-9178 slots showing empty

[technics]

I have a cDAQ-9178 with the following (8) cards installed in order NI-9421, NI-9421, NI-9201, NI-9211, NI-9211, NI-9264, NI-9472, NI-9472. From my notebook running NI Max 14.0 everything works fine. But with the new PC installed on the Test Stand with DaqMX 15.0.1 installed, NI Max does not show the first four cards. I tried the Reset and Self Test but it still shows nothing. There is also a labview executable and when I browse for the channels, only the last four cards show up.

Any Ideas?

Have you tried to pull the modules out and inserting one at a time to see if they show up that way?  Also, have you tried the cards that are not showing up in different slots?

Are the devices showing up in the Windows Device Manager? If so, check out this page: http://digital.ni.com/public.nsf/allkb/D1F1D3FC80E4FFDF86256B410059DE31

Another good step to try is to reset the Device Loader Manager Service. Here is a guideline on completing that: http://digital.ni.com/public.nsf/allkb/0819391CA91B3EB38625731D00024649?OpenDocument

Actually the problem was solved by downloading the Instrument Drivers Feb 2015 from the website. I had assumed this was packaged with NI-DAQMX.
