Links in the table bellow point to installation packages of recent versions
An installation package is a single-file setup program; just run it and follow the instructions. The latest version is always available as foxy-install.exe.
If all you want is to update Foxy executable (and keep your configuration, etc.), just download and unzip the latest executable, stop Foxy service (e.g. by executing foxy.exe -t), copy the dowloaded foxy.exe over the old one, and restart the service (foxy.exe).
