For reasons that are not clear, the InfoPath 2007 form published to a SharePoint library started trying to open in InfoPath 2003 instead of 2007--after weeks of working just fine. Both versions of InfoPath are running on the machines in our office. The error message clearly says "The form template was created with a newer version of InfoPath."
I republshed the form multiple times and made sure they were editable in 2007. I uninstalled InfoPath 2003 but they wouldn't open in 2007 anyway. When we go to the library to create a new form, we conintue to get the same error message.
It seems like something has gottne wired into the form that prompts for InfoPath 2003. Does anyone know how to repair the problem. Republilshing is not working.
