Setting up LabVIEW 7.1 and old PCI cards on another computer, cannot get components to talk to each other

[Dennis_Knutson]

It is impossible for a VI to use a data acquisition device and not reference a driver. You need to grasp some fundamentals. You should know which functions the VI uses to communicate to the cards. I still don't understand why you can't provide that information. Provide the VI or an image of the block diagram. Someone with more than a couple of days of LabVIEW experience can tell by just looking at the names of the functions.

Obviously, I'm still in the process of learning a lot about LabVIEW. However, I'm currently the person in my workgroup who knows the most about LabVIEW. Therefore a large part of this task of getting this huge VI (written sometime around 2008-2009) with many, many, many subVIs, working again on an equally old PC, has fallen to me.

I think at this point, a better option is to try to locate/contact the person(s) who put the system together. Thank you all for your responses.

I don't think the problem is LabVIEW related. If the old program was on a hard drive that was primary, simply moving the hard drive to a new pc as primary would have taken minutes and everything would be working now. It's also hard to believe that in all the years that the program was working, no one imaged the drive and saved it as a backup. Reporting the backup would have copied the os, program, drivers, etc and you would have been running now. I also can't believe you can't post an image of the part of the diagram that uses data acquisition or you can't view the hierarchy and instantly tell.
