Error: Access violation (0xC0000005) at EIP=0x0077c03d4e

[cgalan]

Hi,

I'm running LabVIEW 2012 (64bits) on a Windows 7 (64bits) computer.

When I launch the .EXE I receive a report of Access Violation Exception 0xC0000005 at location 0x0077c03d4e

I'm calling an external DLL where I manipulate a string.

I don't always receive this error. It is random. Most of the times I execute my program perfectly.

Thanks,

Carmen.

Hi, wondering if cgalan evergot this working.

I'm seeing a similar problem, using Labview 2011, and recently installing the executable on a 64 bit windows machine (it's always worked on 32-bit machines).

After reading http://digital.ni.com/public.nsf/allkb/CE69D2C55480900486257B6A0037C327?OpenDocument

I went through looking for Call Library Functions that might be causing the issue.  I found Open Registry, Close Registry, and Read Registry vi's that use this, and changed the file paths as recommended.  No improvement.

Is there an easy way to look for Call Library functions?  These were deep within one of NI's Report Generator vi's.  I'm wondering whether there may be others.
