Tomcat Uninstall Using Control Panel-Tomcat Service not deleted

tomcat9windows-server-2016windows-services

I installed tomcat 9.0.12 using Windows Installer .exe on windows server 2016. It was running fine on port 8080. I had also logged into tomcat service using server admin credentials, not local system.
I wanted to run on port 80 so made the required changes in server.xml but no effect. I reverted the changes(had backed up server.xml).
So I stopped the tomcat service, tried uninstalling using uninstall exe present in tomcat directory but it it prompted me:

No service name specified to uninstall. This will be provided automatically if you uninstall via Add/Remove Programs or the shortcut on start menu. Alternatively, call the installer from the command line with -ServiceName=""

Therefore, I uninstalled tomcat from Add/Remove Programs but tomcat9w.exe in tomcat/bin was not deleted nor was the service Apache Tomcat 9.0 Tomcat9 from services. The service is showing up as disabled in services.msc.
Due to this, I cannot reinstall tomcat as the tomcat installer says service by same name already exists.

What would be the best way to install tomcat now?

Windows – How to uninstall a Windows service if the files do not exist anymore

You have at least three options. I have presented them in order of usage preference.

Method 1 - You can use the SC tool (Sc.exe) included in the Resource Kit. (included with Windows 7/8)

Open a Command Prompt and enter

sc delete <service-name>

Tool help snippet follows:

DESCRIPTION:
        SC is a command line program used for communicating with the
        NT Service Controller and services.

delete----------Deletes a service (from the registry).

Method 2 - use delserv

Download and use delserv command line utility. This is a legacy tool developed for Windows 2000. In current Window XP boxes this was superseded by sc described in method 1.

Method 3 - manually delete registry entries (Note that this backfires in Windows 7/8)

Windows services are registered under the following registry key.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Search for the sub-key with the service name under referred key and delete it. (and you might need to restart to remove completely the service from the Services list)

C# – windows service installer not registering service

Does your service project have an Installer class? You should have one that looks something like this:

[RunInstaller(true)]
public partial class Service1Installer : Installer
{
    public Service1Installer()
    {
        InitializeComponent();
        ServiceProcessInstaller process = new ServiceProcessInstaller();
        process.Account = ServiceAccount.LocalSystem;

        ServiceInstaller serviceAdmin = new ServiceInstaller();
        serviceAdmin.StartType = ServiceStartMode.Manual;
        serviceAdmin.ServiceName = "Service1";
        serviceAdmin.DisplayName = "Service1";
        serviceAdmin.Description = "Service1";

        Installers.Add(serviceAdmin);
    }
}
