This error may occur when you are trying to run a workflow after upgrading to 18.1 version without “killing” UiRobot.exe from task manager before the upgrade or you have installed both 2017.1 .msi
and 18.1 .exe
Troubleshooting:
- Uninstall the 2017.1 version(if you have it)
-
Kill any UiRobot.exe processes from Task manager and run again from Studio. Please note that the updated Studio and Robot will be in this folder:
%localappdata%\UiPath\app-18.1.1
under the names UiStudio.exe and UiRobot.exe - Uninstall UiPath Studio/UiPath Platform and reinstall
