We officially support Director 8, 8.5, and MX on Mac 0S X, Mac OS 9, and 32-bit Windows platforms. PrintOMatic MX will very likely work with versions of Director all the way back to 5.0 on Mac and Windows, however, we are dropping any "official" support for these older versions of Director, because doing acceptance testing on all these older versions is just too difficult. Tester feedback shows that the Xtra also works fine with Authorware, but we don't have the Authorware skills (or a copy of the software) to do this effectively.
