I had SQL Server 2008 R2. But then I need to have SP1. I downloaded
SQLServer2008R2SP1-KB2528583-x64-ENU from Microsoft website and run it. After installation everything was ok, but SQL Server Management Studio didn't work. I downloaded SQL Server Management Studio SP1, but no luck.
After some googling I decided to re-install SQL Server. I totally removed SQL Server and try to run R2 SP1 installer again. But got following issue:
Does anybody know what's problem?
Goto "Programs and Components" and remove "Microsoft SQL Server 2008 R2 Setup". Then, run installer again
