install cf2018
I installed the cf2018 developer version, and the web server config tool is missing in the installation process (it was there in earlier CF versions.). After successful install, i went to C:\ColdFusion2018\cfusion\runtime\bin\ and run wsconfig.exe as admin, got 'another instance of wsconfig seems to be running'

Now the wsconfig can't be launched after installation either, hence I got stuck. What does it mean "another instance of wsconfig seems to be running"? what should i do next, how to get rid of that instance? thanks.
