Just a quick note on what I ended up doing: I already had LV 8 installed on my secondary computer so I am simply using Windows remote desktop from my primary computer to program on my secondary computer. At some point I want to try installing DAQmx 7.4 on a computer that has LabVIEW 8 to see if it will work.

I need to clear one thing up: I am actually using LabVIEW 7.0 to compile the application I discussed but I want to add LabVIEW 8.0 to my development computer to support some of the new programs I am working on. Because I am a developer, I have every version of LabVIEW from 3.1 to 7.1.1 on this computer and wish to add 8.0. The problem has to do with the version of DAQmx compatibility with LabVIEW 8.0 and the older computers I am trying to support.

I haven't upgraded my main development computer to LabVIEW 8.0 because of the following problem: I have an application that I regularly rebuild and distribute to multiple customers (~100 right now). Many of these customers have DAQmx 7.3 installed. LabVIEW 8.0 installs DAQmx 8.0 so when I build my application on a computer that has DAQmx 8.0 the application is incompatible with computers that have DAQmx 7.3. Officially, LabVIEW 8.0 only supports DAQmx 8.0 and unofficially I have heard that earlier versions of DAQmx will work with LabVIEW 8.0. Here are my questions: 1. What is the oldest version of DAQmx that will work with LabVIEW 8.0? 2. Are there any tricks to installing and older version of DAQmx on a computer with LabVIEW 8.0 (and a several older versions of LabVIEW too)? 3. Is DAQmx 7.4.1 forward and backward compatible with DAQmx 7.3? In other words, if I compile with DAQmx 7.4.1 can I run that application on a computer with DAQmx 7.3? I've asked these questions to NI but they haven't gotten back to me with the answers yet.
