Unable to work with SikuliSharp in C#

I am trying to use Sikuli to automate a Windows application developed in WPF by our client. I have checked it directly using SikulixIDE.2.0.5.jar and its working perfectly. But all the data are hardcoded in that. Instead I need to make it dynamic and configurable using an application. So I am trying to build a C#.NET application to configure all these data.

For this I tried adding SikuliSharp from Nuget package manager and tried the below code. But while trying to create a Sikuli session, it fails.

using (var session = Sikuli.CreateSession())
            {

                var nextButton = Patterns.FromFile(@"C:\Automation\Sikuli.sikuli\1715933882452.png");
                session.Wait(nextButton, 5);
                session.Click(nextButton);
            }

System.NotSupportedException: 'Could not find a known Sikuli version in SIKULI_HOME: "C:\NewSikuliSetup"'

Looks like it is trying to identify whether Sikuli is installed in the PC. But it is not yet installed. Below is the Java version installed in my PC.

C:\SikuliFiles>java -version
openjdk version "1.8.0_412"
OpenJDK Runtime Environment (build 1.8.0_412-b08)
OpenJDK 64-Bit Server VM (build 25.412-b08, mixed mode)

After this check, I downloaded the sikulixsetup-1.1.3.jar and ran the command java -jar y"path to the jar file" for which I get the below error. Installation is not successful.
