Word crashes in wwlib.dll

Hi,

I'm not sure whether this is an Add-in Expres issue or not.

We've implemented the IMsoDocExporter interface to create a customized export of Word documents. See: http://msdn.microsoft.com/en-us/library/aa338206%28v=office.12%29.aspx

Everything works well with a 64bit version of Word. But with a 32bit version of Word it crashes in the wwlib.dll (0xc0000005 Access Violation) just before the Document.ExportAsFixedFormat() call returns.

We already invested many hours to find the source the problem but without success. Any ideas how to fix that error?

If it helps I can provide a minimal test project where the error occurs.

Hello Samuel,

Please send us the test project to the support email address, see readme.txt.

What Word version are you using?

Hi Andrei,

I sent the test project and a report of the error.

We've tested it on various Word versions. It did't work with Word 2007 32bit, Word 2010 32bit and Word 2013 32bit.

It works on Word 2013 64bit.

Hello Samuel,

The add-in works fine in Word 2013 32bit, 15.0.4623.1000. I click the button for new empty document created at startup.

Hello Andrei,

Did you click through all message boxes? It crashes after "FinishDocument".

I suggest that you disable other COM add-ins and check if this solves the issue.

We already tried that.

Is it possible that the installer is the problem? I read something that on a 64bit Windows a 64bit installer may write entries to the wrong part of the registry in case of a 32bit application.

On our developer machines are everywere 64bit versions of Office installed. So we were not able to test it on a developer machine directly with a 32bit Word.

I've reproduced the crash after building the setup project and installing the add-in; in my tests I've just registered the add-in from the VS IDE.
