Hi SYCRB560,

Please perform the following steps to manually uninstall the existing SQL Server 2008 R2 or SQL Server 2012.

1. Make sure you have administrative rights on the computer.
2. Uninstall the existing SQL Server 2008 R2 (or SQL Server 2012 ) and all the components from the control panel. Remember to back up the user databases before uninstalling SQL Server.
3. Backup the registry.
4. Delete the following keys in regedit:
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server --HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer
5. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall  and delete all the sub-keys referencing SQL Server.
6. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server.
7. Rename all the SQL Server folders in the computer.
8. Reboot the machine.

Besides, if the above SQL Server components are not listed under Add/Remove programs, you can follow the steps in below similar blog to uninstall them.

Hi LIdiya,

You should not suggest above method of removal if SQL Server has multiple instances, I had a chat with Microsoft Person and according to him this method is only suitable when server has only one instance in other cases it may damage the registry leaving system in un-suppported state

Sorry for previous typo, I should say:

I want to uninstall SQL Server 2008 R2 and SQL Server 2012 but it was unsuccessful.

What did you try to uninstall?

I think you tried to unintall Microsoft SQL 2008 R2 Setup and Microsoft SQL 20012 Setup  ??

You need to right click on Microsoft SQL Server 2008 R2 or Microsoft SQL Server 2008 R2 (64-bit) and then uninstall . Similarly for 2012.

I tried to uninsall SQL Server 2008 R2 and SQL Server 2012.

Yes, I did what you said : right click on Microsoft SQL Server 2008 R2 and then uninstall.

System pop up window says :

Hi SYCRB560,

Are you able to uninstall SQL Server using the MSIEXEC /X {GUID} command as described in the below blog?

Thanks,
Lydia Zhang

Thanks Lydia,

Finally I found the GUID of those programs still left behind in my system, I uninstall those programs by MSIEXEC /X successfully and eventually I can complete uninstall the setup program of SQL Server 2008 R2 and SQL Servier 2012 successfully.

Thanks for all your help and your team as well.

Wish you guys have a great weekend !
