Look in the upper left corner of the screen on the title bar. In Envelope Manager, look for the word "(32 bit)" after the version number. In DAZzle, look for the number 97. If you don't see one of those, you are still running the 16-bit version. You can find the version and serial number of the software you are using by choosing the Help menu (not the Help button on the toolbar) in either DAZzle or Envelope Manager and choosing About.
