  1. If you have Windows 7 Pro you can try to use XP compatability mode. If not, you probably can't run the program. See this post: http://social.answers.microsoft.com/Forums/en-US/w7programs/thread/93a8a175-40fc-4dde-9d23-ef1eb048ff6d/
  2. You'll need to run the app in a Virtual Machine - such as XP Compatibility mode, or VMWare, etc...

    16 bit code will not run in 64 bit Windows: One of the reasons mentioned for this limitation is there are 32 "significant" bits on software 'handles'. A 16 bit app cannot process them, and they can not be shortened without data loss.
