Problems to startup a working station (some controller dont connect)

Hi, I’m new here in that forum

First some information about my used system:

Software:

Robotstudio: 2019.5.4 (64-Bit) Version 7.0.8746.0631

Painting Powerpac 2019.3 Version: 6.10.0034.0069

Hardware:

Workstation Dell Precision Corei9

Memory: 32 GB

Graphic: NVIDEA Quadro P5200

Display: 4k

My Problem is:

Nearly every time, if I open a station, some controllers don’t connect it stops at starting.

If I first open an other station, which brings the same problem, then I can start that station which I want to use without any problem.

As well I’m not able to close RobotStudio with that station, which have the problem, there I have to go to the task manager and kill RobotStudio.

Did any one have this problem and have a solution to solve, I think, that there are starting some processes before it have to…

kind regards
Ralph
