I have downloaded tomcat 8.0.14 (x64 version of windows). I start tomcat with success (I run startup.bat). I have JAVA_HOME, CATALINA_HOME and everything works well!
In my tomcat, here is tomcat8.exe file, i think it it for to register as service. When I double click to it, nothing happens. Here is only black window (CMD) which is for about milliseconds, I cant read even errors too.
