I'm not sure where this query belongs since it mixes both application and Windows "under the hood" level interaction.
A while back I installed the iFilter software from Adobe that allowed Windows Indexing to index both file properties and contents for PDF files. I have very many PDF files and it was a godsend to be able to search them for content when I couldn't remember where, exactly, something was located.
Once I installed Reader XI the indexing of file contents for PDF files became broken and the message "Registered iFilter is not found" is shown in the Advanced dialog for PDF files under Indexing Options.
I have completely removed the previously installed Reader XI as well as the iFilter that had been installed separately, since Adobe claims that the iFilter for X64 systems now comes bundled with Reader XI. The computer was shut down and restarted after the uninstallations, and a fresh copy of Reader XI was installed. This has fixed absolutely nothing.
It seems that there are many, many people with this problem, but very few solutions to it out there. I tried several suggested fixes, none of which worked, before the full uninstall/reinstall.
Does anyone know how to fix this problem (I hope once and for all)? It's a real PITA to not be able to use Windows search to look for content in PDF files.
