Embarcadero's web site seems to be down at the moment, but there is a 
little copied from a message on one of there forums from 1 Feb 2010:

At http://cc.embarcadero.com/Item/27554 you can find the source code for 
a shell extension which can be compiled to a 64bit library using Free 
Pascal / Lazarus. The source code is compatible with Delphi 7 and 
better, too.

If you don't already use www.codenewsfast.com you might search on it for
"explorer shell extension 64" and you'll find several threads about this.
