@tweakimp It seems that running on Windows requires GTK to be installed before in a separate step.

• Do you still get the error if you follow this: https://doc.courtbouillon.org/weasyprint/stable/first_steps.html#windows
• Were you able to start and run the app?
• In the app demo, were invoices rendered as PDF? (Invoice context menu -> View)
