I have SP Designer 2013 and used it to create workflows for our 2013 on-prem hosted sites. So far so good.
I recently got Visio 2013 Professional installed and was excited to try the visual design view and to import/export to Visio. After the install I' restarted my machine and the Visual Designer View and Export to Visio are both enabled in the ribbon. But neither does anything.
I get a progress dialog that says "Generating workflow stencils/Checking if the workflow stencils are already generated" for a few seconds. The progress meter doesn't advance and then it goes away. The view doesn't change, nor does it export a file.
When trying to import I'm asked to name the new workflow, prompted to select the visio file, and then nothing. It doesn't create the workflow and it doesn't import the file.
I've googled on stencils and workflows. I only find MS propaganda about this cool new feature and nothing on it not working.
