Feel the same frustration...
Corporate (or Cisco) has pushed us to the latest/greatest, but on every reboot I'm reminded that "I've made it..", yet following any step suggested results in a "..cant find the original directory that Webex Meetings was installed from" (or similar). Its been a couple of weeks now of seeing this every time I boot, and it's getting old.
Cisco, please make an "Uninstall" application that will forcibly remove your old software and leave the new.
