Juicy topic of conversation. I have seen this. Try clearing “RobotDataGeneration” and then set “RobotDataFolder” to be empty, and then run simulation. It might not work or at least give error that no machine data is in robot.
You might need to reinstall KUKA.Sim or install “EqualizingTech” which KUKA support can help with.
If you want to get down with the sickness, this zip is RobotDataFolder created in VC 4.6 +KUKA OLP with same KR 10 robot, but in VC it has dress pack on it. zhuhge1q.zip (512.2 KB)
There might be something corrupted on the installation, so best to contact Support since they can possibly send you repair package.
Might be related to Engineering Tools installed on your device… is it just KUKA.Sim on your machine or do you also have VC on the machine? Anyway, support most likely has to help or you can try cleaning your machine.
