======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual FoxPro for Windows, version 7.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you run Visual FoxPro 7.0 on a computer with the locale set to a non-English
language that has a corresponding Visual FoxPro run-time file, and you use the
CreateObject() function to create two instances of a single-threaded DLL that
was created with Visual FoxPro, you receive the following error message after
Visual FoxPro creates the second instance of single-threaded DLL:

   Fatal exception: Exception code: C0000005

This error might not occur if Vfp7renu.dll is in the VFP7 home directory or the
default directory.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Visual FoxPro for
Windows 7.0. For additional information, please see the following article in the
Microsoft Knowledge Base:

   Q316964 How to Obtain the Latest Visual FoxPro for Windows 7.0 Service Pack

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Visual FoxPro for
Windows 7.0.

This problem was first corrected in Visual FoxPro for Windows 7.0 Service Pack 1.

MORE INFORMATION
================

Steps to Reproduce the Behavior
-------------------------------

The following steps reproduce the problem when you use the German locale. This
problem occurs in any non-English language that has its own localized run-time
files.

1. Configure the German locale on your computer. Make sure that this is the
   default locale for the operating system.

2. Paste the following code in a program (.prg) file, and then run the program
   from the Command window:

   Set Safety off
     StrToFile( ;
      "Define Class ClsA as Custom OlePublic"+Chr(13)+"Enddefine", ;
      "b010828_1a.Prg" ;
     )
     Build Project b010828_1a from b010828_1a.Prg
     Build Dll b010828_1a from b010828_1a
     StrToFile( ;
      "Define Class ClsB as Custom OlePublic"+Chr(13)+"Enddefine", ;
      "b010828_1b.Prg" ;
     )
     Build Project b010828_1b from b010828_1b.Prg
     Build Dll b010828_1b from b010828_1b
     oRefA = CreateObject("b010828_1a.ClsA")
     oRefB = CreateObject("b010828_1b.ClsB")
   RETURN 

Note that you receive the error that is described in the "Symptoms" section, and
Visual FoxPro quits.

To remove the entries that are placed in the Windows registry by steps 1 and 2,
run the following code from the Command window:

   CD <dir with STDLLs>
   DECLARE INTEGER DllUnregisterServer in b010828_1a.dll
   ? DllUnregisterServer()
   CLEAR DLLS DllUnregisterServer

   DECLARE INTEGER DllUnregisterServer in b010828_1b.dll
   ? DllUnregisterServer()
   CLEAR DLLS DllUnregisterServer
