Can not determine if this program will run on Windows Vista 64bit

Sounds like Compatibility Mode may help.

To configure the compatibility mode for an application, just locate the installation directory and right click on the .exe, selecting Properties from the menu.
Select the Compatibility tab:
You can choose to run the program in Windows XP compatibility mode, or even all the way back to Windows 95 compatibility.
Probably the most useful setting to start off with would be to disable the visual themes and desktop composition, if you can't get things working. If you are trying to run a video game, you will often need to choose "Run this program as an administrator". You'll have to play around with it, but most likely you can get your application working this way.

Good Luck

To be precise if the program uses 16 bit routines (which it does in this case) then unfortunately there is no way it can be installed on vista 64 bit. There may be a version on developers site for this os. If you want to know a solution then it may be virtual pc (search microsoft). The other solution is to install another 32 bit os like xp X-86 version: dualboot.
