1) Install one instance of Tomcat with "install service" enabled 2) Install second instance of Tomcat with "install service" disabled The 2nd installation will modify the existing Tomcat service to point to the new Tomcat installation path. Expected behavior: The 2nd installation should not touch the service configuration since the installer was explicitly instructed *not* to do anything service-related.
The windows installer always installs Tomcat as a service. The text and web site could be clearer about this and I have made some changes. If you want to install multiple services, don't use the installer, use service.bat.
