MOSS February 2009 Cumulative Updates Break 64bit Adobe iFilter v9

After updating a customers MOSS farm with the February 2009 Cumulative Updates and performing a full crawl of my default content source I found that PDF files were no longer being indexed. I discovered that the updates had overwritten a registry key that the Adobe iFilter 64bit deployment guide asks you to change and therefore had changed it back to the default key.

To fix this issue perform the following on your Index Server:

Run Regedit by browsing to c:\Windows\system32\regedt32.exe and double-clicking it.

• While still in RegEdit, within the left-side tree, browse to: \\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Setup\ContentIndexCommon\Filters\Extension\.pdf
  


• Ensure that the values match the following as shown.
  Default = {E8978DA6-047F-4E3D-9C78-CDBE46041603}
