I have installed GoToMeeting Desktop application on My Windows 10 and Windows 7 laptop.
I allowed GoToMeeting on Windows defender firewall.
Am not able to open GoToMeeting Application and join meetings.
Am using Windows Defender Security Center on my Windows 10 Machine
@agiline3 Is that your only firewall / security set up on your Windows PCs?
You could try downloading the GoToMeeting MSI manually, then running the install package as an administrator: https://support.logmeininc.com/gotomeeting/help/install-via-msi-windows-g2m010013
