If the attendee has the GoToMeeting desktop software installed on their computer already, it will launch by default when they join a meeting. If the attendee has the desktop software installed they can type the 9 digit meeting ID directly into the software to join the meeting. After joining from the Web App and attendee can switch to the desktop software (and install it if necessary first), by clicking on the switch icon in the Web Apps control panel. Once they have done this the desktop software will be their default way of joining meetings.
If the attendee is trying to join from a computer that does not meet the system requirements for our desktop software (Linux, old Windows or Mac), we will automatically default them to the Web App so they can still join the meeting.
An attendee can also choose to use the Web App by going to app.gotomeeting.com and entering the meeting ID there. In some cases, the meeting Organizer may share a join link that uses app.gotomeeting.com, this will connect attendees via the Web App by default. This is useful if they have a compatible system but are not permitted to install software.
