You can rename it to .cab and then extract the source files out. Then you can open the manifest.xsf file in notepad, and remove the xsf:header block. When done, right-click the manifest.xsf file and choose design. Then save your template back to a .xsn file.https://www.infopathdev.com:443/forums/thread/1866.aspxWed, 21 Feb 2007 17:09:03 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:1866trentdudei0https://www.infopathdev.com:443/forums/thread/1866.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=39&PostID=1866I've been working on this form the last couple of days. I recently made a change to the 'header' through page setup. When I tried to open the form in design mode I get the following error:<br /><br />The form definition (.xsf) file contains elements, attributes, or structures that are not valid.<br /><br />Error details:<br />Element '<a target="_blank" href=http://schemas.microsoft.com/office/infopath/2003/solutionDefinition}header'>http://schemas.microsoft.com/office/infopath/2003/solutionDefinition}header'</a> is unexpected according to content model of parent element '<a target="_blank" href=http://schemas.microsoft.com/office/infopath/2003/solutionDefinition}printSettings'.>http://schemas.microsoft.com/office/infopath/2003/solutionDefinition}printSettings'.</a><br /><br />Line 188, Position 17<br /> &lt;xsf:header&gt;<br />----------------^<br /><br />How do I get the .xsn open so that I can get to the .xsf?
