I am patching a SQL2008R2 Express Edition instance. On the first failed attempt, all seemed to be fine - SQL loaded, dbs online, @@VERSION returned the expected results, but errors were found during installation.
I had the issue below
The registry key System\CurrentControlSet\Services\MSSQLSERVER\Performance is missing.
For which I followed this post to fix
It seems to have worked. I ran Repair from the setup image. But I am not able to run the patch - the initial screen tells me that the Upgrade Status is 'Installed' - whereas before this Repair fix it told me 'Installation incomplete'.
Can anyone confirm that the patching has been successful? I would think so, as it says there SP3, Installed. @@VERSION returns the correct results, but it already did when the patch was 'incomplete'. Has SQL 'caught up' during the repair, or were the incorrectly installed aspects of SP3 repaired?
Thanks
