RobotStudio .NET exception: Access is denied.

Hi all,

We've been using our IRC5 controller with both robot studio and the PC SDK for about 6 months, every day.
For some reason, on Friday (5th Jan) we can no longer connect through our application or Robot Studio.

This is the error in Robot Studio  (PC SDK doesnt seem to really give much information at all)

RobotStudio .NET exception: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

We've not changed any configurations of the controller/robot/Application.

Any ideas as currently we cant use our machine

Wow this has messed up the formatting!

this can be removed now anyway - it’s due to the latest windows updates as posted by admins on this forum :slight_smile:
