After searching throw internet i found the reason of error on this blog.The reason was a permission peroblem of my serviceAccount. The account was trying to access the VSS registry key and it was failing due to lack permissions.


So here is the fix, just type in regedit.exe in run and navigate the VSS registry key


HKLM\SYSTEM\CurrentControlSet\Services\VSS\Diag


Right click on Diag, go to permissions and give the service account listed under details tab in the error with full control permissions.
This should fix the error, you can check this by restarting the office search service by using

net stop oSearch

net start oSearch

or


stsadm -o osearch -action stop
stsadm -o osearch -action start

If you still run into the same issue, then try the following:

psconfig -cmd services -install

This will configure SharePoint search again.
