HELP: Error when using IMAQ USB

[JieleiNi]

I am a new user. To learn vision acquisition software, I firstly installed "LabVIEW 2012", and then installed "Vision Acquisition Software", and then "Vision Development Module", and finally "NI-IMAQ for USB Cameras". I can see "IMAQ USB" under the "vision and motion" button. But when I run the programme, there is always error indicating as: Call Library Function Node: Library not found or failed to load.

Can you give me some suggestions? Thank you in advance!

IMAQ for USB Cameras is a very old program.  It was merged into Vision Acquisition Software a while ago.  Installing the old software on top of the new software probably corrupted something.

I would uninstall IMAQ for USB, then reinstall Vision Acquisition.  Hopefully that will fix the problem.
