@echo off
REM Register Bambuddy as a Windows service via NSSM.
REM
REM Called from Inno Setup's [Run] section. Arguments:
REM   %1 = install dir (e.g. C:\Program Files\Bambuddy)
REM   %2 = data dir   (e.g. C:\ProgramData\Bambuddy)
REM   %3 = port       (e.g. 8000)
REM
REM If the service already exists (re-install / upgrade), remove and
REM re-create it so config changes from this build apply.

REM Run as LocalSystem (default). Required for binding 322/990/8883 if
REM the user later enables the Virtual Printer feature. Most non-VP
REM workloads would work as a less-privileged account, but service
REM identity changes are disruptive — pick the broader one once.

REM Start the service. If it fails to start, NSSM exits non-zero and
REM Inno Setup will surface this to the user.
