MAX unable to recognize software/hardware

[Peter Lew the Third]

Hi

I re-installed Labview 7.1 multiple times without success. For some reason, the Measurement and Automation Explorer (MAX) does not recognize any of my National Instrument software that I have installed, nor does it recognize the DAQ Signal Accessory device that I have plugged into my PCI-6251 slot. When I open MAX, the software and hardware panel on the left side shows nothing. Has anyone encountered such a problem? What are some possible solutions?

Hi Peter,

It could be that some of the data files that MAX looks at are preventing new information from working.  In order to make sure that some old files are not interfering with your present operation follow the steps below:

1. Go to C:\Program Files\National Instruments\MAX and find the Data folder. 
   
2. Copy this folder to a different location and rename it. 
   
3. Delete the original Data folder.
4. Reboot your computer
5. Launch MAX
6. Refresh Devices (View > Refresh F5)

You should be able to now see your devices in MAX.  If you are still having problems, see if you can run an example program without setting up the devices in MAX.  If you are able to do that we can see if the problem is in MAX, LabVIEW, or maybe the devices cannot be seen by the operating system.

Best of luck!
