I have a forms library in SharePoint 2010. When some people try to open InfoPath forms it seems like the browser wants to open them in the browser and not in InfoPath filler. Since those forms are not browser enabled that does not work. For other people this works as expected.
How does the browser (or Windows) know with which application it should open the InfoPath forms? I have tried the file extensions, but this is XML and XML can be multiple things. Where can I configure that InfoPath forms should be opened in InfoPath Filler and not in the browser?
