I have installed "SQL Server 2008 R2" with an instance name "SQLEXPRESS". Then I found out it cannot restore from my older "SQL server 2008" backup files .
So I uninstalled SQL Server 2008 R2 and installed back my older SQL server 2008 with an instance name "SQLEXPRESS2008". Now I could successfully restore my backup files.
The problem is that for some reason I have now two SQL server instances (SQLEXPRESS and SQLEXPRESS2008). I would like to delete SQLEXPRESS.
Following suggestions on the web, I tried going to "Control Panel"/"Programs and Features", asked to Remove "SQL SERVER 2008" (2008 R2 was not in the program list). A window opened which offered me to select an instance to remove. While the Installed Instances table did show both instances, the drop-down selection box only offered me to remove SQLEXPRESS2008.
Any ideas how I can remove the SQLEXPRESS instance?
