In LoadRunner Controller, error "-1" appear while running test

Please find the screenshot as attached.

Once starting to run test in Controller, there is a "-1" shown for error immediately. 

Clicking the number and error message prompt "Registration Failed - Could not register this client. Check the --resultPath argument".

I check different video tutorials and it should be displayed as "0".  I wonder if any action I can do to fix it ?

Also, Is there any other way to view those specific error quickly during script run? It is not efficient to check the whole Vuser Log.
