I am trying to install self-built extension for Opera . As Opera suggests :
1.One method is simply dragging .xml file to opera.And it gets installed in developer mode. Also it works pretty fine in my case.
But the second method:
2.Zip the folder and change name from .zip to .oex. Now drag it to Opera.
And it gets installed.This doesn't work.
I get the following popups
And when I click OK.I get the following message.
Anyone can tell me what is the problem.
Still the First method works completely fine. And the Extension is also working fine.
