Again a very helpful Post - but - (of course there is always a but)
I was facing the same issue and thanks to a post from @Iyce_Winsoft I was quickly able to fix it. So again thanks for that Iyce.
What I was wondering about, as the Rooky I am, was why this was necessary.
After installing UI Path everything worked fine. I started to do the foundational training and suddenly nothing was working anymore. OK, but why!?
To make it short, hoping that this will help other rookies when searching for this topic.
When you reproduce the steps in orchestrator following the first tutorial video you will register your first Robot and switch it to connect. Congratulation you managed to register the robot but you also turned off the user mode and switched it to a service. Presumably without knowing about this 2 states at this first stage after letz say some 25min of video – like me.
Finally, just hit the disconnect Button on the Robot settings, lean back, watch the other vids and continue having fun.
