Start UI.Vision macro from Windows command line

I try to start an UI.Vision macro from the Windows shell (cmd.exe), but get the following (german) error message:

“Der Befehl “macro” ist entweder falsch geschrieben oder konnte nicht gefunden werden.”
(in English about: “The command “macro” has been misspelled or could not be found”)

I put this string in the windows shell:
start firefox file:///C:/Users/hanomas/Downloads/

When I put the string directly in the browser line, then it works and the Macro starts.

Thanks for help

Change to

"C:\Program Files\Mozilla Firefox\firefox.exe" "file:///C:/Users/hanomas/Downloads/"

Or your correct path to firefox
