Hi @cc c ,
itdoesnt work ,even uninstall SQL Server and reinstall cant help me. I have tried many ways like use REGISTER but all doesnt work.
And before reinstall, please follow the below steps to remove all components of previous installed SQL Server completely:
- Remove all SQL Server components from 'Programs and Features'
- Backup the registry
- Delete the following keys in regedit:
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
--HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer - Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and delete all the sub-keys referencing SQL Server
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and delete all the keys referencing SQL Server
- Reboot the machine
In addition, please use an administrator account to reinstall SQL Server on your computer(Right click->run as administrator).
Regarding the registration form, did you follow the article? Do you still get the same result as the picture?

Fix1 is to check whether the .net framework is started. You can skip Fix2 because you mentioned that But my MMC is running correctly. Fix3 is to find the CLISID in question and delete it. Finally, you can try Fix4. If you have checked and tried all of the above Now, you can uninstall sql server cleanly and reinstall it.
If there are any new errors in the process, please let me know, it will help solve the problem.
Best regards,
Seeya
