I dont know if you already did it or not...

In these scenario's I will try to do a repair the SQL Server installation first...
Then try to stop the SQL Server instance, if it is an enterprise then I will bring the whole box down for the time (remove it from the network)

Then try to remove the SQL server.

hi
I have tied to repair the installation, to no luck. this happened after an upgrade to the SQL installation from 2008SP2 to 2008 R2 which some how left remnants of the original installation behind and continued to upgrade or in this case unsuccessfully removing components before installing new ones.
I could then see a new upgraded instance still holding the same information but not operational.

when running a complete uninstall it then shows 2 installed instances (old and new) which only the new instance can be uninstalled.

I then followed these steps to try remove all instances http://blogs.msdn.com/b/baliles/archive/2012/04/27/how-to-fix-a-failed-sql-2005-2008-r2-or-2012-install-upgrade-mssqlserver-inactive.aspx
which did successfully remove all instances but I still have 2 SQL products in my installed programs.

when I uninstall Microsoft SQL Server 2008 R2 Setup I get the attached warning message
"Warning 26003. Microsoft SQL Server 2008 Setup Support Files cannot be uninstalled because the following products are installed:
SQL Server 2008 SP2 Common Files
SQL Server 2008 SP2 Database Engine Shared"
SQL Warning

hi

I managed to resolve issue with these steps:

:
1.      Remove all SQL Server components from 'Programs and Features'
2.      Backup the registry
3.      Delete the following keys in regedit:
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
4.      Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall  and delete all the sub-keys referencing SQL Server
5.      Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server
6.      Rename all the SQL Server folders in the computer
7.      Reboot the machine
8.      Install SQL Server 2008 R2 again
