If you have a Windows 10 computer, you don't need to install PrimoPDF. Windows 10 includes a PDF printer driver.
In order to generate a PDF file, use any TournamentSR print feature (e.g. "Print"/"Print ladders"/"for programs"). In the resulting window, change the "Printer:" setting to "Microsoft Print to PDF". This is an option just like any actual printer your computer knows about. Click the [Print]/[Print all] button. You will be presented with a window asking for the name of the PDF file to generate.
