I was also facing the same problem. I just downloaded newer version and installed it. Problem got solved. So it seems this problem occurs because of older version of Android studio.
Found a temporary solution from Issue #170850
Add the following code to C:\Program Files\Android\Android Studio\bin\idea.properties
disable.android.first.run=true

It looks like a older version of Android Studio is the culprit. Try downloading from here: http://developer.android.com/sdk/index.html
Open the folder "bin" under the directory where you installed your Android Studio. Find the file "idea.properties" and open it with Notepad++/UltraEdit/other_edit_tools. Add "disable.android.first.run=true" as the final line and save the file. Restart Android Studio
