Fatal Error When Using Signal Express

Updated Oct 25, 2019

Issue Details

Signal Express 2015 crashes when I attempt to utilize the interface. The error states: Fatal Internal Error: "memory.cpp", line 342 LabVIEW version 8.2.1.
How can I resolve this error?

Solution

This issue is usually due to using incompatible versions of DAQmx with Signal Express. You can check the compatibility of Signal Express with your software by going to the Signal Express readme

The latest compatible version of DAQmx with Signal Express is version NI-DAQmx 9.5.5 or later. If you have an earlier version installed, uninstall that version of DAQmx to be replaced with a new version after 9.5.5., and then force reinstall the Signal Express software to resolve this issue.
