I have 2009 and 7.1 on the same machine. When I install DAQmx 9.0.2 for 2009, all my acquisition vi's for 7.1 (installed with NI-DAQmx 8.9) go missing. Is there a way for 7.1, 2009, and DAQmx 8.9 and 9.0.2 all to co-exist on a machine? Currently, I am having to uninstall and install the acquisition drivers each time I switch LV versions.
You can only install one version of DAQmx. You can, however, install multiple versions of LabVIEW. Unfortunately, there is no DAQmx version that supports both 7.1 and 2009.
Hi, there is a thing to do before installing DAQmx, save repertory of LV7 and after install ofDAQmx copy the save and all working well. (only express will not work).

I doubt this will work. While the VIs may be there, the underlying DLLs that get called are different. At the very least the code will likely not even run.
Rats. But, I have do find that an executable made with 7.1 seems to work with DAQmx 9.0.2. Maybe this makes perfect sense? I don't know. Can I rely on this?
for me it is working, still have LV7.1 8.2 8.6 and 2009 on same computer no problem with old VI before DAQmx 9.0.2 to work with. It was same when update to LV8.6 there was no support DAQmx for LV7.1 and NI support said to me to do like this.

I will still no doubt give your suggestion a shot. Didn't have a chance yesterday. Hopefully today. For this project I am only concern with basic I/O functions. One of smercurio's post makes me wonder if certain acquisition vi's will work (if new and old .dlls are the same or similar) while others will not (if new and old .dlls are significantly different).
I can only speak for a handful of the basic IO vis, but your idea to copy the 7.1 folder, install DAQmx 9.02, then copy back the 7.1 folder, is so far working.
