Robot Goes In Pending State And Stuck With An Error As Robot Licensing Failed There Are No Available Runtime Licenses

Resolution when Robot goes in pending state and gets stuck with an error as Robot Licensing Failed. There are no available runtime licenses.

Error Message: When running 2 Robots on the same server, with 2 different users accounts. At a given point only 1 Robot user is able to acquire the license. When Robot user 1 completes a job, the license is not released automatically and the Robot user 2 is not able to acquire license automatically.

Hence due to this, the jobs scheduled for Robot user 2 are staying in pending state with an error as "Robot Licensing Failed. There are no available runtime licenses. (#1915) ."


Resolution: The above error warning is the expected message when the number of Robots are more than the available runtimes. But there is a issue in 2019.10.x Robot doesn't start automatically and stuck in pending state.

Perform the below,

  1. Login machine with user 1
  2. Open the system tray from bottom and quit the UiRobot showing there
  3. Signout user1 from the machine.
  4. Perform the above three activity for user 2 as well
  5. Now run process from Orchestrator
  6. Make sure to quit the UiRobot from Robot tray. The "UI" symbol in the Robot tray should not be available and then sign out from both users
  7. It should be possible to run the Robots on both users.
