Failed to install virtual controller

anton77

Hi everyone

I am trying to install a virtual controller for 3D printing following the instructions from the tutorial https://www.youtube.com/watch?v=MrdsMN2sEAk&t=84s
But in the end, I got a failure message as on the screenshot
 

What am I doing wrong?

I use RobotStudio 2020.2 (64-bit) Version 20.2.9116.0, RobotWare 6.11.01, and 3DP PowerPac 2020.2
