I've recently upgrade from Adobe PDF IFilter 6.0 to Acrobat Reader 9.4. From my understanding, the IFilter will be automatically installed when I install Acrobat Reader 9.4. However, this does not seem to be the case as our index services do not appear to be properly indexing PDF files now. I'm on a Windows 2003 SP2 Standard Edition (32 bit) and we are using Index Service 5.x. How do I get Index service to use the new IFilter? I have checked the registry key, "[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex\DLLsToRegister", and manually put in the location of the new IFilter but nothing seems to work. Anyone have any idea???
