Error:  Found key 'HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\InstalledInstances' in registry
Despite the message states:
Found key 'HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\InstalledInstances' in registry
, the key does not exist in mentioned location. The error was not properly handled. It was caused by software issue PPA-2380. The fix is included in MU #12.
Update PA to the latest version:
- Remove service node from PA.
- Remove corresponding database server from Infrastructure > Database Servers.
- Re-deploy OS on the service node from scratch.
- Re-add service node to PA with required roles.
