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](https://forums.robotstudio.com/discussion/10367/hresult-0x80070005-e-accessdenied-while-trying-to-connect-to-controller)” and tried most of the solutions but none worked.  
Has anyone solved this issue.

Thank You

I have the same issue. I am desperate.  
I have Windows 10 64bits and I have installed RobotStudio 6.06  
Does anyone know what the problem is?

The solution seems to be here:

I have proved it and it works very well.

I thought so, as the update was the only thing that could have changed my settings in the past few days.  
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!
