Unlicenced copy of NI Vision?

[dpg1]

Hi,

I'm running a program I've developed which uses Vision VIs. I've packaged the VI using the Application Builder into a .exe and am running it on a lab computer which only has an expired version of LabVIEW installed, though it does have a activated and active Vision Runtime Licence. I thought this would be suitable to run the program, and elements of the program do work. However, the Light Intensity Histogram which I need to use does not function correctly, and I get the error; "-1074396157 - Unlicensed copy of IMAQ Vision."

Does this mean the Vision Runtime Licence isn't suitable to run this program?

Thanks,

David

I have struggled with this in the past and spent meny hours before getting an answer.  Your application will check the vision development lisence before the runtime lisence as dumb as that sounds.  So a valid runtime lisence will not woek if you have the vision development module on that pc that is expired.  I found that once I removed the development module, then the runtime lisence kicked in no problem.  I do not know if there is a way around this without removing the developmant module (which I know is inconvienent because it closes editing to code on that PC without reinstalling the module).  Hope this helps.  I hade this issue in Labview 8.51 have not tried this again since (you might be able to make a dual boot disk, One as a temporary development system and one with just the exe and runtime).

Did you just uninstall the developer module or is there a workaround to this.  Sometimes I would like to test my system without removing the development module until I ship it, right now have to take a leap of faith that this will always work.  The liscence manager should be able to handle this conflict without a workaround but I have not found one.

Sorry I didn't reply earlier - from my desk computer I can't post on the forums - only read (yet I can accept solutions or post kudos!).

I uninstalled the developer module. For me it's not a big deal as I won't be purchasing the VDM for the PC that is only designed to run the program, but I can certainly see the problems it could raise.
