Problem starting the Virtual Controller

Hi all,
I just ran Robot Studio today and I got this error:
Exception: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) 09/01/2018 16:57:19 General
I looked at this discussion “ABB Robotics Community - Maintenance” and tried most of the solutions but none worked.
Has anyone solved this issue.

Thank You

Thank you for the solution

Windows security updates again in March 2020 made the communication problem with the controller. I uninstalled the recent Windows update and RobotStudio is working!
