Hi Nambabwe, if the test panels button is greyed out for a device, that means that MAX was unable to load the nidaq32.dll driver. I am interested in figuring out this problem, because it seems to be a commonly reported problem, yet I cannot reproduce it myself. Here are a few questions for you:
* Which version of NI-DAQ are you using?
* If this version is equal to or greater than 7.0, do you have both Traditional NI-DAQ and NI-DAQmx installed, or just Traditional NI-DAQ?
* Regarding the non-administrative users who are running into this problem: are they restricted users, power users, or guest users?
Here's one possible solution off the top of my head:
The "CurrentFile" value of the registry key "HKEY_LOCAL_MACHINE\Software\National Instruments\NI-DAQ\CurrentVersion\Configuration Manager" indicates the location of the current DAQ configuration file. Ensure that your normal users have at least read access to this file (and this registry key too, but it sounds like you've already done this).
Please check back with the answers to these questions, and I will help to come up with a solution to this problem.
Joe
