While starting the emulator I'm getting Emulator Error?

While starting the emulator I'm getting the following error. If anyone can solve the problem please share with me.

Emulator: Fatal: This application failed to start because no Qt platform plugin 
          could be initialized. Reinstalling the application may fix this problem.  
Emulator: ((null):0, (null))
Emulator: Process finished with exit code -1073740791 
          (0xC0000409)

Did you actually try reinstalling the application as it says in the error output? Also, here are some answers that could help you with your problem
