Hello, Jonathan! Thank you for a quick response and detailed answer! Thank you I configured the setup with the default settings. I do NOT have the C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Log\ERRORLOG path on my file system. Seems like setup has failed despite what was returned by the wizard.
How would you recommend unistalling SQL Server in a correct manner. I mean there a gazillion of entries in the Add and Remove applet related to SQL Server. I even have two records for Microsoft SQL Server 2008 R2 (64-bit) there. Also, I have SNAC, setup support files, and R2 Setup (english). Which item you would recommend me to start with the uninstall?
