+SETUP STEPS:
+.	Install Java stack  on Server  JRE 8u111x64
+.	Run install.bat in AdFrom ministrator CMD
+a.	Installation takes place in c:\program files\Java
+b.	Executable are below c:\program files\java\jre8\bin
+.	Using c:\program files\java as execution folder for the san quorum IP
+a.	Copy the latest ip_quorum.jar in that location
+b.	Download the service wrapper from https://repo.jenkins-ci.org/releases/com/sun/winsw/winsw/2.9.0/  (winsw-2.9.0-bin.exe   (Project page https://github.com/winsw/winsw)
+c.	Copy the executable inside the same folder as the ip_quorum.jar
+.	Preparation for creation of the service:
+a.	Rename the winsw-2.9.0-bin.exe to the same name as the desired service name in our case to: sanquorum.exe
+b.	Create a wrapper xml for the service which needs to be names sanquorum.xml
+c.	Content is described on the github site.
+d.	Here is our content:
+<code>
+<service>
+  <id>sanquorum</id>
+  <name>SANQUORUM</name>
+  <description>This service runs the SAN Quorum Java script.</description>
+  <env name="SANQUORUM_HOME" value="%BASE%"/>
+  <executable>"%BASE%/jre8/bin/java"</executable>
+  <arguments>-jar "%BASE%\ip_quorum.jar"</arguments>
+  <log mode="roll"></log>
+</service>
+</code>
+.	Install the service:
+a.	From an ADMINISTRATOR cmd navigate to c:\program files\java
+b.	Run "sanquorum.exe install sanquorum.xml"
+c.	The service is then created
+.	Start the service:
+a.	Run "sanquorum.exe start sanquorum.xml   or got to the services console on the server and start the service
+.	Check status:
+a.	Look into the services console or run sanquorum.exe status mysanquorum.xml
+b.	There are also various which are created once the service connects properly to the svc/san in the same Java folder
