My Windows 10 x64 computer currently has version 10.12.0 Build 18425 installed.
When I start GoToMeeting, then click On "Participate", then, in the Installation directory
the folder 18068 is set up with the GoToMeeting version 10.11.1 Build 18068.
This version will then also be started automatically for the Video conferencing.
Is this an error or is it correct?
It depends upon what software version the organizer account is set to, which dictates the version every participant launches when joining the meeting.
