On two different Windows 10 Pro notebooks, I tried to join a WebEx meeting using Internet Explorer and after installing the add-on I get a modal window telling me "Windows cannot find 'C:\Users\Me\AppData\LocalLow\WebEx\WebEx\1524\atinst.exe'. Make sure you typed the name correctly then try again."
If I remove the add-on and instead choose "Run a temporary application" I can join.
Any suggestions, other than use what works?
