 The service name uses a double slash (`//IS//runner`) — this is the procrun syntax for "install service". `--Jvm=auto` lets procrun locate `jvm.dll` automatically from `JAVA_HOME` / the registry. The stop is delegated to `stop-runner.bat` through `cmd.exe`; the full path to `cmd.exe` is required because procrun passes `--StopImage` directly to `CreateProcess`, which does not search the `PATH` (a bare `cmd` fails with `The system cannot find the file specified`).

+@tab Alternative (more logging, `jvm` mode)
+
+With `--StartMode=java`, procrun launches the Runner as a **separate** `java.exe` process and does not pipe that process's output into `--StdOutput`/`--StdError`, so `runner.log` can stay empty. Use this `jvm`-mode variant instead: procrun loads the JVM **in-process** and captures the Runner's `System.out`/`System.err` directly into the log file.

+runner.exe //IS//Runner ^

+:::warning Set `--Jvm` to your real `jvm.dll` path
+In `jvm` mode, `--Jvm=auto` often fails with `no JVM configured or found in registry` (many JDK/JRE builds don't register in the Windows registry, and the `LocalSystem` account doesn't see a user-level `JAVA_HOME`). Replace `<JAVA_INSTALL_PATH>` with your Java installation directory (the same path as `JAVA_HOME`).
+
+Note that `jvm` mode replaces `--StartMode=java`/`--StartParams=-jar#runner.jar` with `--StartMode=jvm`, `--Classpath` (the path to `runner.jar`) and `--StartClass` (the Runner main class). The `runner.exe` (procrun) and the `jvm.dll` must be the **same architecture** (use the 64-bit `prunsrv.exe` from `amd64\` with a 64-bit JRE/JDK).
