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.
SQL Server Setup has encountered the following error:
Method not found: 'Microsoft.SqlServer.Configuration.Sco.SqlEdition
My SQL Server has encountered an error
The problem is there is conflict between the old version and to a newer version of SQL Server that you are about to upgrade. To ever come this problem, you need to delete files which is related to old version when you installing new version. There is another solution which is very easy. If you run the installer, run in with admin rights. You may do that by right click the installer and choose run as administrator. If there is still problem with the installation, you must check your installer, maybe there are some corrupted files form it that’s why you encounter error.
