Hi!

I’m trying to run e-series 5.11.1 URsim remotely from a docker container (running nvidia/opengl image + openjdk-8), however, when trying to `start-ursim.sh UR10` I get the following error:

```auto

Inside the tar file you will find the folder /usr/bin. You can copy the content to /usr/bin of the host.

Thanks for your comments!

After correcting some small error on my side and implementing this solution the problem is fixed and URsim works.
