Looking at the path in your pic, it looks like you have the steam version.
Did you download the free steam version then purchase a key direct from Scirra?
If so, download construct2 from scirra too, then put your key into \Program Files\Construct 2\ .
If you download the free edition from Steam then upgraded to the full version through steam, steam handles the licence file for you, you should not have to put it there yourself.
This should help -
