Hello, I'm from México and I'm currently studying a master's degree online and the University is using GoToTraining.
When I first tried to join a session, I received this problem "GoToMeeting ran into Technical Problems. Please try again." so I installed it on my Cellphone and all good but, since my University some times requires me to do some presentations or share screens I do need it on my computer so I tried to install it again and nothing, same error.

I'm not able to join any session on my PC, I tried reinstalling everything, deleting temp folders, registry, rebooting my PC but is always the same error.
Windows 10 Home (Partitioned, Windows 10 files inside C drive and User Data / Programs inside D drive).
