Problem with starting the process

I started the process on the robot machine and it tells me an error.
Did anyone know how to solve this issue?
Thanks in advance.

Hello, can you please provide more information on what your app is doing with screen shots?
This could be caused by a number of issues like if you are using an Excel and it is open when the app is started to a variable not being declared.

Try to repair your Excel using the Repair Tool for Microsoft Office from UiPath Studio → Apps

UiRobot.exe execute --file "C:\UiPath\Automation\Project.json" :warning:
UiRobot.exe execute --file "C:\UiPath\Automation\Main.xaml" :warning:

Important note: :warning: not supported for Windows or Portable projects.

Otherwise, you will see an error as such:

You can only run .NET6 .nupkg files or published process from the UiRobot command line.

Here’s an overview of the process

How far does the app get before stopping/error?
When the CSV is downloaded is there any pop-ups?
Pretty sure something with the Excel is causing the issue.


stop before this part.

I would put a breakpoint in at that section and check your file paths are correct, use writeline and check them.


Stop working on this part.

Looks as though your Excel sheet is the cause, try to repair it as stated earlier.


Hello @dvojinovic

Please try to create a very simple project with a message box and try to execute directly with robot.exe. As per my understanding some kind of version issue is happening for some package.
