I am working on converting some SharePoint 2013 Workflows to Visio so I can use the Workflow Converter from Nintex. I currently have SharePoint Designer 2013 64 bit & Visio 2013 Professional 64 bit. When I open SharePoint designer, then go into a 2013 workflow, the option to export to Visio is greyed out. If I open a SharePoint 2010 Workflow, then the Export to Visio option lights up. Any ideas?
