Ok, So I have spent the better part of a month trying to get Infopath 2003 forms to function in Infopath 2010 without success.
Background here:
http://www.infopathdev.com/forums/t/18454.aspx
So at this point the only alternative as far as I can tell is to Uninstall Infopath 2010 Designer & Data Filler from the Office 2010 Suite and re-install Infopath 2003.
Will this create any conflicts?
Also, are there any viable alternatives to Infopath out there?
