IFilter problems with LibreOffice - Primary search method failed. 0x80cbc100 (0x0) - :30

Question

When I search ODT documents with Agent Ransack I get an error message:

"Primary search method failed, raw data search used. Loading stream
into filter failed. 0x80cbc100 (0x0) – :30"

and the search hits are embedded in something that looks like HTML.

I have LibreOffice installed along with the Microsoft Office IFilter pack.

Answer 1

The problem appears to be related to an incompatibility with LibreOffice and the MS Office IFilter pack. When LibreOffice is installed although the MS Office IFilters objects can be created they do not appear to be able to load any documents.

The simplest solution is to simply 'Repair' the LibreOffice installation via the Add/Remove Programs control panel settings. This should reset all the registry settings to point back to the LibreOffice IFilters.

More information

The registry points to the appropriate IFilter for a given file type. If you look at the registry key for ODT files:

HKEY_CLASSES_ROOT\.odt\PersistentHandler

the (default) value will point to the registry key to look at for the IFilter settings. For MS Office it points to:

{34CEAC8D-CBC0-4f77-B7B1-8A60CB6DA0F7}

and for LibreOffice:

{7BC0E713-5703-45BE-A29D-5D46D8B39262}
