InfoPath Dev

I had a form that worked fine and still does on my pc and others except for one pc.  The form is designed in 2007 infopath, saved as 2003 with backward compatible 2003 vb code.  Form is not a web form.

 The user that the form does not open correctly on was using infopath 2003, and he has since been upgraded to infopath 2007.  All office 2007 components have been installed.  He can open the form and it opens it in a webpage with the xml(source file), it does not open in infopath 2007.

 Any suggestions?  Thanks.

It sounds like InfoPath is not registered wityh windows as the default application to open XML or XSN files.

You could save one of each locally.

Right click and select open with and then manually set InfoPath to always be opened for these files.

Or probably a reinstall or repair of office would fix it too.
