Run-time error"31003" -unlicensed copy of IMAQ Vision

[AlWave]

Hi there,

I have a proper licensed copy of IMAQ. I use it for my VB6.0 application. The apps runs fine with other functions of IMAQ until I call "ParticleReport" function.  I got this error showing "Run-time error 31003, unlicensed copy of IMAQ Vision". Does anyone come across this before? any suggestions to resolve it?

thanks

AlWave -

What version of IMAQ Vision do you have?

Is your IMAQ Vision licensed?  To determine this, run the NI License Manager (under Start->Programs->National Instruments), and look for "Vision".

Do you get the same error if you call the "ParticleMeasurement" function on the CWIMAQVision control?

Did this issue get resolved?

I am using VB6 and using IMAQdx & NIVBAI. Everything has worked well until this morning when my customer reported this error. All software is licensed and verified under the license manager. Any ideas?

After investigating further, I wanted to post some additional information regarding my problem. 

The error message only shows when I have the following command in my code:

CWIMAQVision1.Rotate CWIMAQViewer1.Image, myImage, 180

Before this step executes, I can successfully call commands with CWIMAQViewer1 and NIVBAIInspection. 

When I look into the license manager, I do not see Vision as an option. I would think that this would be using the same drivers for all CWIMAQ related calls.

Thanks in advance for any help you may have!
