I am trying to create a fillable form using a Word (.docx) form, but I receive this error. It appears this error has been an ongoing issue in LiveCycle Designer for several years with no clear fix or information from Adobe's knowledge base. Adobe needs to increase its backend support services and make it more intuitive or automated.
