vision usb camera error

[LHX]

Hi,

I am using LabVIEW version 9 and Vision Acquisition software together with a USB 2.0 digital camera. My error is that when i run my VI, the Vision Acquisition software can't find the camera but it can find it only if the VI is not running. (Attached below is the error that I get). How do I solve this issue?

Hello LHX, 

Are you still encountering the same error?  

When you say that it "can find it only if the VI is not running", can you elaborate on this statement? Are you able to see your USB camera inside of Measurement & Automation Explorer (MAX) and are you able to successfully grab images from there? That will be the first thing to check. Because if it cannot grab images inside of MAX, then you will not be able to in your VI. 

You also may want to verify that your Vision Acquisition Software (VAS) license is indeed activated for you computer. You can check this by going to the NI License Manager program.

No I've already solved it, it was because I didn't program my codes properly.

But thank you for your reply!
