Unable to open Android Studio because files are locked

"Files in C:\Program Files(x86)\Android\android-studio\system\caches are locked.
Android Studio will not able to start up"

Yeahhh!! this is the error I get when I am trying to open my Android Studio with Windows 7, but, it is as simple to fix as right click over Android Studio icon -> Run as Administrator.

that's all
