Enable arm on selection not working from options.txt

[mantaranos]

Hi,
I want to enable the arm-on-selection option.
Therefore I created an options.txt in my Live 11.3.3. folder under preferences and wrote "-EnableArmOnSelection".
When opening Live the following message appears:


What am I doing wrong here?

Edit:
Ok sorry, I've got it working.
What I did wrong was to create a rtf-file and then simply change the ".rtf" to ".txt". It worked when I created a "real" .txt file.

Thanks for sharing how you fixed it.
