Downloads
The setup is the normal Windows install path. The portable ZIP is available if Windows treats the setup download aggressively. The standalone EXE remains available for direct launch.
The app can run an online update check from Help or the tray menu, verify size and SHA256, and start the installer on request. After 60 days from the first detected update it shows only the installation notice until updated.
Windows note
Windows SmartScreen may warn for new or low-reputation software even when hashes match. A publicly trusted code-signing certificate is not currently configured; a local test signature is not shipped because self-signed certificates do not create public trust.
