C# exception thrown at 0x73406EAD (clr.dll)

I have an exception and I'm not really good at dev to find a solution. I import serveral dll's. I have an exception:

Exception thrown at 0x73406EAD (clr.dll) in YourApplication.exe: 0xC0000005: Access violation reading location 0x00000200.

My visual studio debug output is :

I update the dll. Still the same. This application works on an other computer. Perhaps I need to update my clr ?

EDIT : To be more specific. The exception was thrown at this line :

DllImportHelpers.CheckResult(MyDllImport.MyFunction(_handler, UInt32.Parse(_aWidth)), "MyFunction", DisplayName, messages);

The function call from MyDllImport is:

[DllImport(MyDllName, CallingConvention = DllImportHelpers.DllCallingConvention, CharSet = DllImportHelpers.DllCharSet)]
public static extern error MyFunction(IntPtr generator, imn_uint width);

This call is for a low level function. This only return an error if the generator is null.
