Using Microsoft Word 11.0 Object Library In Deployments

I should clarify my original post by noting that the error occurs when I run the app after having deployed it on another machine, not during deployment.

I just tried to run it on a machine that has Word 2003 and I got the same error.

Here is the stack trace:

Microsoft.Office.Interop.Word.Documents.Open(Object& FileName, Object& ConfirmConversions, Object& ReadOnly, Object& AddToRecentFiles, Object& PasswordDocument, Object& PasswordTemplate, Object& Revert, Object& WritePasswordDocument, Object& WritePasswordTemplate, Object& Format, Object& Encoding, Object& Visible, Object& OpenAndRepair, Object& DocumentDirection, Object& NoEncodingDialog, Object& XMLTransform)

How are you deploying the app? Through an MSI or xcopy?

"When I create a deployment package and run it on" should have told me that you were using an msi.

Both just in case one method might've been the problem.  Below is the code that contains the documents.open method throwing up the error:

could it be that the install is not shipping all needed dll´s...
are you creating the msi by adding project output -> primary output?
and does the resulting msi package install all of the needed interop dll´s?

Definitely not that.  It chokes on that method, not on the creation of the Word Application object which is what would happen if the dependency was missing.  I have noticed that in my code it requires 16 arguments for Documents.Open() but for the previous Word object library it would require 15.  That suggests there might be some sort of compatibility issue but then how to explain the same error on a user's computer with Word 2003?

Actually scratch that.  The user I thought had 2003 reverted to 2002.  So it's some sort of backwards compatibility issue.

sounds that way... if you don´t need any specific 2003 functionality couldn´t you try to create the project with say a word 2000 reference and see if that would work with 2003 and 2002

I can't because I only have the object library for the version of Office installed on my machine.  Shouldn't there be a way to make it backwards compatible using the 2003 library?

Those 2 links had what I needed, thanks a lot.

glad to help. good luck.
