This is the full Cambridgesoft Chemoffice 2002 (7.0) suite.

Chemdraw itself will run under OS 9 and OS X (I'm currently running it
on 10.5.8). The rest of the applications in the suite will only run
under OS 9, and run poorly in Classic mode. Functions like the NMR
predictor do work well under OS X.

There are known compatibility issues with all versions of Chemdraw
with copying structures into and out of Office 2008 programs. This
issue is not present with older (and newer) versions of Office.
Structures will copy fine into a Word 2008 document, but can not be
copied back into Chemdraw. If you require this functionality, use Word
2004, 2001, or X.
