IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, see Microsoft Knowledge Base article 256986.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

If the specified key was manually deleted and it is the only key missing, it may be possible to restore the key from a backup of the registry. Depending on the key, some values may be server-, instance-, or catalog-specific, and the values may not be the same on different instances or over time. If the key cannot be restored, you may need to reinstall MSSearch, Full-Text, and/or SQL Server, depending on the key.

If the key exists, either the Search startup account or the SQL Server instance startup account will need to be granted sufficient permissions on the specified registry key, depending on which process failed.
