Issue Details

I am trying to open DAQExpress and I get the following error message related to NI-DAQmx:


The behavior described above is more likely to be related to installation issues, which is common with new installations. To troubleshoot the error, follow the steps:
  1. Uninstall and install the NI-DAQmx driver. If this option is not possible, then try repairing the driver and software.
  2. My next suggestion involves a reset of the NI-MAX database. First, make sure you have any configurations of NI-MAX saved if you would like to keep them. Next, within NI-MAX, go to Tools, and then Reset Configuration Data. Retry launching DAQexpress.
