Polyflow will run outside of Workbench, you'll need to export the working files (I don't know the format as I don't use Polyflow) and then launch from the Start menu.Â
The problem is not the file format as such, but that models may or may not be available in earlier versions of the code. So, the format is technically unchanged but the data stored may be different.Â
