Why Do I Get Access Violations in Windows NT at "0xC0000005, Assert in Menu.c Line 2441" with LabVIEW 5.0.1?



Primary Software: LabVIEW Development Systems>>LabVIEW Full Development System
Primary Software Version: 5.0.1
Primary Software Fixed Version: 5.1
Secondary Software: N/A

Problem:
I'm running LabVIEW 5.0.1 on a Windows NT 4.0 Service Pack 3 computer. Launching LabVIEW from the Start menu or double clicking on a desktop icon results in a Dr. Watson report of Access Violation Exception 0xC0000005 at location 0x0073DAB1. I also receive a DAssert in e:\lv50\mgsource\menu.c line 2441 if I Search Examples.

Solution:
The problem occurs when you have seven or more paths in your editRecentPaths entry in your preferences file. In this case, LabVIEW disposes of all paths in the recent file list. The first time you try to access one of these paths, you'll experience a crash.

This is fixed in LabVIEW 5.1 and higher. However, if you continue to use LabVIEW 5.0.x, then you must edit the labview.ini file located in the C:\Program Files\National Instruments\LabVIEW 5.0.1 directory to make the following changes:
    editRecentPaths=""
    menuSetup="Default"
