Linux: make the file executable once, then start it: chmod +x JTDX_contest-*.AppImage and ./JTDX_contest-*.AppImage
Windows: the installer is not code-signed, so SmartScreen may warn about an unknown publisher. The SHA-256 above identifies the file you downloaded; SHA256SUMS holds all four lines.
macOS: the app is not signed with an Apple Developer ID, so the first launch is refused: open it once and close the warning, then go to System Settings > Privacy & Security, scroll to the message about JTDX_contest and click Open Anyway. macOS also allows less shared memory than the program needs - JTDX_contest offers to raise that limit itself and asks for your password once.
