Following Command is utilized for installing SQL SP3 pack in Windows server 2008 R2.
start /WAIT C:\Temp\SQLSP3.exe /quiet /IAcceptSQLServerLicenseTerms /Action=Patch /AllInstances
This complete installation is happening in Administrative Privilages.
This installation failure is not happening in all server but only in fewer servers.
But i am getting the following error code in installation.
In control panel , it seems that SQL SP3 pack was installed
and SQL server still refers SQL 2008 Service Pack 1.
Please help me.
