Iā€™ve got exactly the same problem, launched or not with admin rights, the message ā€œPermission missing; Launcherā€ appears.
Iā€™ve the community edition, and trying the evaluation version (with license), my own script and site samples gives same results.
Do you mean that without this license I cannot use the community edition ?

Have you tried what @ddpadil suggested? In my opinion itā€™s related to the admin permissions.
Did it worked before? Does this happen after you installed the latest studio version?

I had to remove all traces of UIPath on my machine, once I did think I was able to install again and it worked. No idea what the problem was though

This got resolved by reinstalling the trial version again.Seems something related to different versions being installed in my desktop.Thanks for the response guys :slight_smile:

ā€˜Permission missing: Launcherā€™ error is received in the following scenario:

  • robot is connected to orchestrator with user ā€œabcā€
  • on the robot machine you try to start robot (from tray or studio) with user ā€œadminā€

Let me know if you have other questions.
