How do I recover my license?

Why won't Kanmail start on Windows?

Windows users: Kanmail needs Microsoft's WebView2 runtime. The Windows installer adds it automatically if it's missing; if Kanmail still won't start, install WebView2 from Microsoft and try again.

Why won't the Kanmail AppImage launch on Linux?

Linux users: AppImages need execute permission before they'll run. After downloading, mark the file executable with chmod +x Kanmail-*.AppImage, or right-click the file in your file manager and tick Allow executing file as program. AppImage also relies on FUSE — most distributions include it by default; on minimal installations you may need to install libfuse2 (or fuse on older distros).
