Issue Details

While using the Measurement & Automation Explore (MAX), an Unexpected Error dialog similar to the one below pops up. What are these exceptions? Is it safe to ignore them by selecting the Do not show this error again option?
 

Solution

MAX has the ability to detect exceptions thrown by internal plug-ins. Some of the exceptions are benign and do not negatively affect normal operation in MAX.

If this is the first time you've seen this error, restart your computer first. The error sometimes occurs after installing new NI software and not restarting the PC.

Here is a list of the current known exceptions. If the exception is benign and does not negatively affect your system, you may select Do not show this error again in the error dialog to prevent it from displaying again.
 
 
# Plug-In ExceptionBenign?

Additional Information

This error can also occur if software was not installed properly or is corrupted, and can be fixed by reinstalling. Follow this article to Force Reinstall Non-Working or Corrupt NI Software, or remove DAQmx and all dependencies and install the software after a restart. A common cause of unclean software installs is having anti-virus software, so make sure to disable anti-virus.

This error is similar to another error that occurs when upgrading to NI-DAQmx 18.0 or 18.1 while using a real or simulated FieldDAQ device.  See Internal Warning when Upgrading to NI-DAQmx 18.0 or 18.1 with FieldDAQ  for more information on how to resolve this issue if you encountered this issue after upgrading to NI-DAQmx 18.0 or 18.1.
