In a previous blogpost, i mentioned that SQL Server 2008 R2 halted when trying to install over SQL Server 2011 Denali. After uninstalling Denali when i again run SQL Server 2008 R2 following error message was generated
Failing in clean install of SQL Server 2008 R2, i tried to upgrade an existing SQL Server 2005 instance to SQL Server 2008 R2. But upgrade process also generated following error message
- Remove 100 folder from ‘C:/ProgramData/Microsoft/Microsoft%20SQL%20Server/’. It may be left by any previous failed installation or uninstall of SQL Server R2.
- Run SQL Server 2008 R2 set up by Admin rights on Windows Server 2008 or Windows 7. You may do it by right clicking the set up file.
