Hi everyone,

I am trying to get the Remote TCP & Toolpath URCap working in my UR simulator. However, whenever I try to start the controller in the installation tab of the URCap, I get the status: “Failed”.

Details:

- Polyscope version: 5.19
- URCap version: 1.4.2
- VM software: VirtualBox

Has anyone experienced this issue or have any insights into what might be causing it? Any guidance would be greatly appreciated!

Thanks in advance!

I have the same problem, same Version 5.19 and URCap 1.4.2 and VirtualBOX

I tried this from 2020  
[Remote TCP & Toolpath URCap Controller Start Failed - URCap Development / URCaps SDK - Universal Robots Forum](https://forum.universal-robots.com/t/remote-tcp-toolpath-urcap-controller-start-failed/8252)  
but it didn’t work.

Has anybody a solution?
