An error is reported when running tomcat9w.exes from the folder
The error prompt box is unable to open the service tomcat9
The method is actually very simple: open DOS, (that is, "start" + R, enter cmd), enter the bin directory of the file where tomcat is located
Tip: Enter cd . . to exit the current path, and cd to enter the path. Not much to say, the picture above! (Note, this is my path, you can go in according to your own installation path)
Then enter service.bat install in the bin directory
service.bat install
Then it can be opened normally after installation.
