Newly downloaded Tomcat8.0 unzip run Tomcat8.exe screen Flash on the run Tomcat8w.exe pop up a basket
The specified service does not exist with the installed services unable to open the service ' TOMCAT6 '

I installed TOMCAT8, double-click Startup.bat can start Tomcat normally, can also display http://localhost:8080/, but looks like the installation version of the bad use. After uninstalling, some of Tomcat's services were uninstalled. Double-clicking the green version of Tomcat7w.exe appears "The specified service does not exist with the installed service", "unable to open the

Service "Tomcat8".

= = Enter the tomcat installation directory ==> enter the bin directory ==> input: Service.bat Install
