CustomAction Orchestrator_ConfigureIis returned actual error code 1603

Error Message:
" CustomAction Orchestrator_ConfigureIis returned actual error code 1603"

Root Cause:
One of the reasons for this error is if the Orchestrator service name from IIS \ Application Pool is changed to something else, then the error would occur during the upgrade.

Resolution:

  • CustomAction Orchestrator_ConfigureIis, it typically points to issues related to the configuration of IIS during the upgrade.
  • Make sure that the Orchestrator service App pool name is "UiPath Orchestrator".
