I should have been more specific. We're running Office 2016 on the desktop, all 32-bit including InfoPath. We also have O365 and SharePoint in the cloud. My co-worker has exactly the same setup & I can use his forms w. no problem.https://www.infopathdev.com:443/forums/thread/118878.aspxWed, 25 Apr 2018 16:05:30 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:118878Hilary Stoupa0https://www.infopathdev.com:443/forums/thread/118878.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=118878Are InfoPath and your Office install the same bitwise? i.e. both are 32 or both are 64 bit? Have you installed all software updates?https://www.infopathdev.com:443/forums/thread/118876.aspxWed, 25 Apr 2018 15:57:42 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:118876brutchersp0https://www.infopathdev.com:443/forums/thread/118876.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=118876Hi, hope this isn't a duplicate. I'm working in an enterprise environment. I recently upgraded to from Windows 7/Office 2010/SharePoint 2010 to Windows 10/Office365/SharePoint 2016. I have InfoPath Designer 2013. I can create & publish new forms and edit & publish existing forms. However, when I try to USE the forms I receive the following error message: The form contains XML that cannot be parsed: An invalid character was found in text content. Line 1, Position 5 MSCF ----^ This occurs whether it's a web-enabled form or a filler form. I have exported & examined the source files. None of them contain invalid xml as far as I can tell. The "MSCF" referenced in the error message is at the top of template.xsn - which obviously isn't an xml file. Another user with the same system setup is able to create & edit forms and I am able to open and use them. This leads me to think there may be a problem with my individual InfoPath configuration. I have not tried re-installing InfoPath yet. Thought I'd ask here before invoking the nuclear option. Any help anyone can provide will be appreciated. SB
