Hello Prasad,
1. Running tests through the Test tab via Quick Execution will not populate the Results tab. You include one or more tests in a Test List, and then execute the list.
2. Once the Calendar view on the Results tab is populated with result rectangles, You must double click on one of them ("FF4" under the 5-24-2011 column, in your screen shot, for example). This "drills down" into the result to load it. The Word and Excel Export options are then available.
Kind regards,
Anthony
