Windows Screenwriter 6 won't run or crashes on launch? RESET your default print driver

Windows, especially Windows 10 and 11, occasionally "forgets" the default printer settings, especially after updates. Screenwriter 6 requires a printer driver (not a physically connected printer) to be added to the system. The reason for this is that printer drivers contain the paper size information, which allows Screenwriter to correctly calculate page length. This can result in all sorts of problems, such as being unable to open documents, unusually long or short pages, weird margins, and potentially crashes.

The solution is to (re)set the default print driver:

• Click on the Start icon in the lower left corner of your screen
  
• Open the Windows Control Panel (you can search for it using Cortana, the Windows search feature)
• Select Hardware and Sound
• Select Printers or Devices and Printers
• If you see the Microsoft XPS Document Writer there, right-click on it and set that as the default printer. This is Windows' generic print driver that also happens to support exporting to PDF. Alternatively, select the printer you use and set IT as the default printer. The important point is that a default printer is set.
  • WINDOWS 10 and 11 users may need to do these extra steps to set the default printer

    • when you click on the printer, you'll get a button to "Manage" the device:

       

    • Then, when you press that, on the "Manage your device" page, you'll see a button that says "Set as default"
• In Screenwriter, go to File > Print Setup and make sure the Microsoft XPS Document Writer, or your actual printer is selected.
• Make sure a default page size is selected, such as Letter or A4.
• Press OK.

IMPORTANT NOTE: There is also a checkbox, "Let Windows manage my default printer" -- this should NOT be checked.

ALSO: some users have noted that after a Windows Update, they need to restart their computer. If the above steps don't solve the issue for you, please try restarting your computer.
