Error - Unable to locate nicdxu.dll ?

Recommended Posts


My programs have been working fine until today, when I ran a simple program to write digital signals to a USB-6009 DAQ card. I'm currently using XP and NI-DAQmx 8.1.0.

The error that came up when I ran it was:

"Error: Labview.exe - Unable to Locate Component

This application has failed to start because nicdxu.dll was not found. Re-installing the application may fix this problem."

What should I do? I tried searching, and I thought it may be a corruption in the MAX database, so I went through this KnowledgeBase article: http://digital.ni.com/public.nsf/allkb/2C7...D9?OpenDocument, but that didn't help.

Actually now, the device won't pass the self-test.

Just very confused at what's happening. Thanks for any help,
