I formatted my system after taking backup. When restored and tried running the code I got the following exception  
cinder::app::ExcRendererAllocation at memory location 0x0019F968

Placed all the folders correctly as it was before formatting the system.  
What additional changes I have to make so that project would work as before?

Sounds like you need to update your OpenGL drivers.
