The alternative installer can only upgrade Tomcat instances it installs. (It can't upgrade instances installed using Apache's installer or manual installations; it doesn't know about those.) The process in your case would be something like this: 1. Document the Tomcat service installation details for the instance you want to replace and back up its config files. 2. Remove it (reverse whatever process you used to install, whether Apache installer, manual, etc.). 3. Install using alternate installer; e.g.: apache-tomcat-a.b.c-setup.exe /instance="FOO" 4. Update the config files, copy application server files, etc. See the documentation - https://github.com/Bill-Stewart/ApacheTomcatSetup - for details. (Without /instance it installs a default instance - i.e., default directory of "\Program Files\Apache Tomcat", "Apache Tomcat" as the service name, etc.) To upgrade (in general): 1. Touch (update timestamps of) config files you don't want the installer to overwrite. 2. Run the above install commands with the new version of the installer. Don't forget the /instance parameter if you used it to install initially (otherwise, the installer will install or upgrade the default instance). Note that each instance installed using the alternate installer (default or otherwise) installs to a separate directory and appears as a separate entry in the Windows "installed application" list. (This is typically the expected behavior for application installations on Windows machines.) I certainly don't claim that the alternative installer is suitable for all applications and configurations, but for fairly common use cases on Windows machines, the two-step upgrade process noted above (I think) is pretty simple.
