Sometimes when you log into a device for the first time, LetMeIn enrollment will pop up. In the username box, you will see "Name-" in the username field and you will be unable to delete it.


Solution:

Press the escape key on your keyboard in the top left. This should remove the word name from the field and allow you to type in your username normally. You will now be able to enroll in LetMeIn and login normally.
