Is it possible to use Open Office where applications are calling Word OLE objects?
===

Ok so we purchased a piece of software that opens, updates, and closes Word documents stored on a file server. I have spoken with the developers of the software inquiring about using other Office systems instead of Microsoft Office. They informed me that they are calling in code Word OLE objects to open, update, and close documents. Which then inherently calls WINWORD.exe.  

Is it possible to configure Windows 7 to open oowriter instead of winword when winword.exe is being called?

The problem we are facing is that new clients don't have Microsoft Office they are running Open Office.
