Hello, Any time we try to launch the application it immediately crashes. The users are logging into a windows 2008 r2 server terminal environment. I have attached screenshots of the event viewer logs. What's really strange is that for one user it actually did work for a week then randomly stopped. The only difference from the user that was working for a bit compared to the user that has never worked are the permissions. windows has been completely updated including .net runtime and visual c++ 2015. I sent in the 3CX logs in and all they can see are that connections are dropping.
