“The instance name must be the same as computer name.”
Fortunately the steps to rectify this are pretty simple as follows:
1. Connect to the SQL Instance using Management Studio and identify the current name
2. Next we need to drop this server name as displayed
3. Now we need to add the correct server name
4. Finally Restart the SQL Service Services
That's it, now when you re-run the installer and perform the system checks, the error should not appear.
