is DAQmx and LV 8.0 compatible with vista

[falkpl]

I think I know the unfortunate answer but I made some minor (mostly cosmetic changes) to an application previously developed with LV 8.0 daq mx 8.4? (HS-DIO calls) and windows XP.  I recompiled under 8.0 and Vista (New daq drivers as well 8.5?) and sent it to run on the same PC with XP.  Program loaded fine executed but no DAQ communications.  I am trying to see if I changes code by mistake or is there an incomaptibility with daqmx and labview 8.0 compiled with vista but run on XP.

LV 8.0 is not officially Vista compatible.  The first version rated Vista compatible is LV 8.2.1.  Using different drivers doesn't help your cause, but sometimes doesn't cause problems.

The easiest way to determine for sure if you've run into a Vista incompatibility is to take the original code that worked and rebuild it in Vista and see if it runs on the XP PC.
