My SQL Server has encountered an error
After failure to install SQL Server 2008 R2 first I tried to upgrade an SQL Server 2005 to SQL Server 2008 R2 but I failed again because the upgrade process generated an error. I need a solution to fix up the problem. If anyone could give me any suggestion I would be pleased highly.
Error:
SQL Server Setup has encountered the following error:
Method not found: 'Microsoft.SqlServer.Configuration.Sco.SqlEdition
Microsof.SqlServer.Configuration.SetupExtension.PidPublicConfigObject.GetRequiredEditionFromMedi
a(Microsoft.SqlServer.Chainer.Infrastructure.ServiceContainer)'
