X-com for 64 bit vista?

does anyone know if there is a version of X-com UFO defense force that runs on 64 bit vista, i know they have versions for XP and such and was wondering if anyone knows of a patch or version of the game that would run on vista. Thanks

As far as I know, you only have the XP Collectors Edition.

EDIT:

Just a suggestion: You can try getting the DOS version, patch it up and run it through DOS Box...
