I was attempting to Install SQL 2014 on my Windows 10 (Pro) machine. The installation failed to install the engine, reporting services, analysis services.. it reported an "Invalid Driver" error as the cause... Going back to retry adding those features failed to work, as the setup tool reported them as installed.. So I went through the control panel and Uninstalled all the SQL server components ... now when I attempt to re-install SQL Server, I get to the step to specify the Instance name.. I'd prefer to continue to use the default "MSSQLSERVER" instance name, however the install fails, telling me that the instance name is already in use..
How can I remove the instance name ? I uninstalled SQL Server already... ? how is the instance still registered as in use?
