"first try/attempt" (solving a problem)

[photekxl]

Первая попытка is the first thing that comes to mind.

Any other suggestions? The context is that this is one of the options in a drop-down menu in a program. After solving a software/hardware issue, the technician must choose one of the following: completed (first attempt), completed (second attempt)...etc.

Большое спасибо!

I can't think of a better one. Sounds good to me.
