Vlad Drumea fixes an installation problem:
I’ve needed to run the repair process in the following cases:
- An instance or some of its components become corrupted or missing after OS patching.
One of the most common examples I’ve ran into is SQL Server Configuration Manager being gone from the machine.
Not to be confused with database corruption.- A failed or cancelled SQL Server instance upgrade or patching.
- SQL Server failing to uninstall.
From what I’ve seen, this tends to be a side-effect of the first scenario in this list going undetected.
Read on to see what you need to have and how to perform the task.
