Hello Aadesh,

Thank you for the reply, but I have already installed the iFilter using that link as well as going through the configuration document and am still getting the same thing. When I rerun the installer, i get the options to repair and remove.

Thank you,

Matt

Hello,

This is still occurring after the index.

Here is the message from our user.

I restarted my system and when I left Thursday I started a reindex.

Today when I got to the office I checked and the pdf documents are using the correct ifilter (at least it says it’s correct), but none of the content is being indexed.

Thank you,

Matt

I just go this to work.

- the download now is for 11.x.x.x -- this looks like they just updated it to follow Acrobat 11. It works fine even though Acrobat X is installed here (with Reader 11).

- first key to getting this to work: uncheck the pdf file format from the Advanced settings panel, and accept via Ok, which will close that panel.

- second key is to pause the search service, from the initial Indexing panel, and wait until it is paused, before you do the installation.

- wait some moments until the panel indicates indexing is paused. It will probably say paused for 15 minutes, which is the time you have to install the iFilter.

- Now and only now run the iFilter installer.

- Go back to Indexing Options->Advanced->File Types, check-mark pdf for indexing, and make sure the radio button for "Index Properties and File Contents" is selected. When you do this, instead of seeing the "Registered iFilter is not found" message in the "Filter Description" column you should see "PDF Filter" there instead.

- when you accept and close the Advanced panel, I think indexing will automatically clear and start indexing again. Your pause will be finished..If somehow it doesn't, clear the index yourself to get things going again.

Indexing is pretty fast -- mine has done 200,000 files in a bit over an hour with a fast laptop machine idle, running Windows 10. Pdfs can now be found...

Wow... several years later and this is still an issue. I am on Win10 and the search index config shows "Registered IFilter is not found". The link you provided is for several operating systems but not Win10. What is the fix for those of us on Win10?

Many thanks! I live and die on being able to search my data!
