Error- While starting Rails Server

I have installed ruby 2.0.0p247 with rails(4.0.0) and mysql2 (0.3.15) in Windows 7 After creating a new project when i try to run the server it terminated saying that

This application has requested the Runtime to terminate it in a unusual way.

I also tried the same in Windows 8.1 but still same error exists

Look in development.log (and/or in the server terminal window) and you should get more information.

You may find it difficult to get help for Windows problems as most rails developers use Linux (eg Ubuntu) or Mac where it is generally considered that rails development is significantly easier.
