Java runtime
VisualRoute 14.2b requires a 64-bit Java Runtime Environment, version 11 or later. Most modern Java distributions are supported, including Adoptium Temurin, Oracle JDK, Amazon Corretto, and Azul Zulu.
To check if you already have Java installed and which version:
- Open a command prompt and run
java -version. If Java is present, it will report the version and whether it is a 64-bit build.
Older or 32-bit Java?
VisualRoute 14.2b will not run on 32-bit Java or on versions earlier than 11. Install a current 64-bit build before running the installer.
Firewall
If you run a software firewall, add VisualRoute.exe and java.exe to its allowed applications. VisualRoute needs outbound access to port 80 (HTTP) and port 43 (whois) for full reporting.
