IMAQdx Camera USB shows up in Ni-MAX, not in Examples Imaqdx

[odauchot]

I am new to the forum.

Please forgive any mistake.

Versions informations:

Windows 7 64bit

Labview 12.0.1 64 bit

NI Max 5.4

IMAQ 4.7.2

IMAQdx 4.1

I have two USB camera, one from Pixel-link, the other from Veho.

Both drivers are installed. Both camera are recognized by the PC

Both Cameras are seen by NI-MAX as IMAQ-dx devices and I can grab, snap and save an image from NI-MAX

When I open Labview and run any example from the IMAQ-dx library, I always get the error code -2147220969 from the IMAQdx Configure Acquisition.vi.

Thanks for your help

If you are using 64-bit LabVIEW you will need to ensure you have proper 64-bit driver pieces for your DirectShow camera from your camera vendor. If they only have 32-bit pieces then it will only work in 32-bit applications (NI-MAX is 32-bit). Generally both 32-bit and 64-bit pieces should be installed on an x64 system to ensure it works with any application.

Thanks a lot. I tested it on another PC where I have Labview 32bit and indeed it worked perfectly well.

Now I have installed Labview 32bit together with the Labview 64bit on the first PC.

Shall I also re-install Vision, or can I tell Labview 32bit that it is already installed?

At present the Vision vi's are not found by Labview 32bit.

Thanks
