Service from another Instance Not Removed During Uninstallation

[MithileshL-26]

Hello @oleg-shilo,

I'm installing an application that includes a Windows service. I have multiple instances of this application installed. Each instance installs its own service, for example:

Default instance installs: TestService Second instance installs: TestService_SecondInstance

Code for the Windows Service:

new ServiceInstaller
{
     Name = "TestService_[INSTANCEID]",
     DisplayName = "[SERVICENAME]",
     Description = "test",
     StartOn = null, //set it to null if you don't want service to start as during deployment
     StopOn = SvcEvent.Install,
     RemoveOn = SvcEvent.Uninstall_Wait,
     DelayedAutoStart = false,
     ServiceSid = ServiceSid.none,
     FirstFailureActionType = FailureActionType.restart,
     SecondFailureActionType = FailureActionType.restart,
     ThirdFailureActionType = FailureActionType.runCommand,
     RestartServiceDelayInSeconds = 30,
     ResetPeriodInDays = 1,
     PreShutdownDelay = 1000 * 60 * 3,
     Account = "[USERNAME]",
     Password = "[PASSWORD]"
}),

Problem:

When I uninstall the default instance using Windows Add or Remove Programs (ARP), its corresponding service (TestService) is correctly removed.

However, when I uninstall the second instance, the associated service (TestService_SecondInstance) does not get uninstalled.

Any solution that will remove services from other instances during uninstall?

morning, i dont think it possible in your way. both MSI´s doesnt know each other if both of your msi with windows services are in separate msi. Solution is BA Installer.
preudo code , not tested

public override void Run()
{
    Engine.Detect();

    if (Command.Action == LaunchAction.Uninstall)
    {
        Engine.Log(LogLevel.Verbose, "Starting uninstall of all chained MSIs...");

        Engine.Plan(LaunchAction.Uninstall);
        Engine.ApplyComplete += (s, e) => Engine.Quit(0);
    }
    else
    {
        Engine.Plan(LaunchAction.Install);
        Engine.ApplyComplete += (s, e) => Engine.Quit(0);
    }

    Engine.Apply();
}

Each MsiPackage will receive the uninstall signal and remove its own service only if its ServiceInstaller is correctly configured (i.e., RemoveOn = SvcEvent.Uninstall).

When RemoveOn = SvcEvent.Uninstall, the service gets removed immediately—even if it's still running. This behavior wasn't what I wanted, and I had discussed it earlier in issue #1781.

I haven't tried your suggested solution yet. Instead, I created a separate custom action and added a check, which worked for me
