How to Deal with LabVIEW Crash Reports
LabVIEW is a powerful and versatile software for graphical programming and data acquisition. However, sometimes LabVIEW may crash unexpectedly and display an error message like this:
LabVIEW 20xx encountered a problem and needs to close. You can help us diagnose and fix this problem by sending this report directly to National Instruments.
LabVIEW crash reports are files that contain information about the state of LabVIEW and your computer when the crash occurred. They can help you troubleshoot the cause of the crash and find a solution. In this article, we will explain how to access, read, and send LabVIEW crash reports, as well as some tips to prevent LabVIEW crashes in the future.

How to Access LabVIEW Crash Reports
The location of LabVIEW crash reports depends on your operating system and LabVIEW version. Here are some common scenarios:
If you are using LabVIEW NXG on Windows, you can find the crash reports in the directory C:\Users\\AppData\Local\National Instruments\\ErrorReports, where is your account's folder.
If you are using LabVIEW 2011 or later on Windows, you can find the crash reports in the directory C:\Users\\Documents\LabVIEW Data\LVInternalReports\LabVIEW\\, where refers to your user account's folder. This directory contains folders for each LabVIEW crash. Each individual folder contains a zip file for each complete crash report. Each crash report contains at least a LabVIEW log as .txt file, and a crash dump file in .dmp format.
If you are using LabVIEW 2010 or earlier on Windows, you can find the crash reports in the directory C:\Users\\Documents\LabVIEW Data\lvfailurelog\, where refers to your user account's folder. This directory contains crash log files in .txt format for each LabVIEW crash. Each crash log file is stamped with the date and time of the individual crash occurrence.
If you are using LabVIEW on Mac OS X, you can find the crash reports as .log files in the /Library/Logs folder, which is in a hidden directory. To see this folder, open Finder and press Command+Shift+G to open the Go To Folder dialog. Type /Library/Logs to open the folder containing the crash reports.
If you are using an executable built with the Application Builder (a built .exe application that uses the LabVIEW Run-Time Engine) on Windows, you can find the crash report in the LVInternalReports mentioned above, but under the executable's name. For example: C:\Users\My User\Documents\LabVIEW Data\LVInternalReports\My Application\.
How to Read LabVIEW Crash Reports
LabVIEW crash reports contain different types of information that can help you identify the source of the problem. Here are some examples:
The LabVIEW log file (.txt) contains information about LabVIEW's internal state, such as memory usage, loaded modules, error codes, etc. It also contains a stack trace that shows which functions were called before the crash.
The crash dump file (.dmp) contains a snapshot of LabVIEW's memory at the time of the crash. It can be opened with a debugger tool such as Visual Studio or WinDbg to inspect the values of variables, registers, etc.
The error message displayed by LabVIEW may also contain a hex code that indicates the type of exception that caused the crash. For example, 0xC0000005 means access violation, which means that LabVIEW tried to read or write to an invalid memory address.
To read LabVIEW crash reports, you need some knowledge of programming and debugging techniques. You may also need to refer to other sources of information, such as your code, hardware configuration, system settings, etc. If 06063cd7f5
