You might also want to check out the LabVIEW player. You can find more information on it at the following page: http://zone.ni.com/devzone/conceptd.nsf/2d17d611efb58b22862567a9006ffe76/87392d1cb3c49dde86256ae30049ce55?OpenDocument
There are some restrictrions to it including that the VIs you are trying to read must be signed and the person who signed them will need LabVIEW 6 Professional Development System or higher.
For your case, obtaining an evaluation copy of LabVIEW would probably be the best route.
