RE: weird ACCDDS.DLL error
Hello Dave,
I think this may occur on a 64 bit machine running .net 2.0. ACCDDS
assemblies have unmanaged code in them, so they always need to be run in
the 32 bit runtime. "BadImageFormat" is referring to the format of the
dll, it means .net tried to load a 32 bit only assembly into the 64 bit
runtime. I found the following msdn blog article related to this topic:
http://blogs.msdn.com/joshwil/archive/2005/04/08/406567.aspx. According to
the article, this BadImageFormatException error may occur in the following
three scenarios:
1.anycpu.exe -- runs as a 64-bit process, can load anycpu.dll and x64.dll,
will get BadImageFormatException if it tries to load x86.dll
2.x86.exe -- runs as a 32-bit process, can load anycpu.dll and x86.dll,
will get BadImageFormatException if it tries to load x64.dll
3.x64.exe -- runs as a 64-bit process, can load anycpu.dll and x64.dll,
will get BadImageFormatException if it tries to load x86.dll
Hope this helps to troubleshoot the issue on your side. And if you need any
future help, could you please elaborate a little more about the problem?
Which kind of project we are working on? And, how do we reference the
ACCDDS.dll in our project? With more information, I can try to reproduce it
on my side.

Re: weird ACCDDS.DLL error
Hi;
Sorry - I should have given more context. This occurs when running a
PowerPoint AddIn under the VS 2005 debugger (must use 2005 because we
have J# code) on Vista 64-bit and Office 2007.
Our AddIn is built as "any CPU" but my understanding is that AddIns
are always called in 32-bit mode from Office.
Is this enough to tell us how to work around it?
thanks - dave

Re: weird ACCDDS.DLL error
Hello Dave,
Thanks for the information. After reviewing your first post, I found the
log mentions that "Native image will not be probed in LoadFrom context".
So, I try the following codes on my side:
public void OnConnection(object application, Extensibility.ext_ConnectMode
connectMode, object addInInst, ref System.Array custom)
{
try
{
Assembly.LoadFrom(@"C:\Program Files (x86)\Microsoft
Office\Office12\ACCDDS.DLL");
applicationObject = application as PowerPoint.Application;
addInInstance = addInInst;
}
catch (Exception ex)
{
Debug.Print(ex.Message);
Debug.Print(ex.StackTrace);
}
}
It pops up the exactly same exception message as you post:
"System.BadImageFormatException: Could not load file or assembly
'file:///C:\Program Files (x86)\Microsoft Office\Office12\ACCDDS.DLL' or
one of its dependencies. The module was expected to contain an assembly
manifest.". I think this issue may result from calling Assembly.LoadFrom()
to load a native dll. And, the problematical codes may exist in our Add-In
or one of its referenced assembly. Could you please help to check the
ex.StackTrace's content which tells where the exception comes from.
And one more thing to mention, could you please tell me what's the
objective to load ACCDDS.dll and how we are loading it now? Native dlls are
supposed to be loaded via native api LoadLibrary instead of the
Assembly.LoadFrom() method.
