Sorry brothers..
I found out the reason...
In properties window of SQL management studio/compatibility/
i enabled to run this program in compatibility mode for service pack 1
Thats the reason.. I encountered the error..
But i have the prob to install SP1 on sql server 2012..
I am not able to do it on a developer server...
Can anyone suggest me some ways or any clue i am missing...
I upgraded on the instance of my machine.. it worked fine...
from sqlserver 2012----------> sql server 2012 sp1------> sql server 2012 sp1 cu4
But the same way i tried with one of my developer server but i failed...
Do any one know what could be the possible reason...
:hehe:
