The specified service does not exist with the installed Service.

Symptoms:

I don't know why I can start it today. I thought it was not an environment variable. Haha, the configuration is still not working. It turns out there is no right remedy,
If the service (server) does not exist, add the service to it.
The following are some online statements that can solve the problem.

The newly downloaded tomcat6.0 uncompress. After running tomcat6.exe, the screen will pop up a basket without running atat6w.exe.
The specified service does not have unable to open the service 'tomcat 6' with the installed Service'

Double-click at6w.exe, but "the specified service does not exist with the installed service", "unable to open

Service "tomcat6 ".

Later, I found the cause. It turns out that this service was not installed. Installation Method: Open the command line Prompt window

=> Enter the tomcat installation directory ==> enter the bin directory ==> enter: Service. Bat install.

It is not allowed to click the bat directly in the directory. If the bat fails to run, it will flash through.
