Eventually! Adobe has released a 64bit version of it’s PDF iFilter for Microsoft Office SharePoint Server 2007, Microsoft Exchange Server 2007 and Microsoft SQL Server 2005. Up till now, your only options were Adobe’s 32 bit version, or buy the 32- or 64-bit version from Foxit Software.
Feedback from the field indicates that the Foxit iFilter seems to achieve higher performance, but the Adobe iFilter is free. So go and test yourself and see what your experience is.
