Hi,
The Student version of LabVIEW is the same wherever you buy it. The reason why there seems to be 2 different versions is because if you buy the text book bundle, then that comes with LabVIEW 7 Express, whereas if you buy the software suite, that includes LabVIEW 7.1 inc 14 toolkits.
You can check the different packages available from the ni website at the followig link:
