vision sub-vi won't load on smart camera

[DMT]

  I'm programming an NI-1722 smart camera in LV 2012 on W7-64.  I've successfully written a program to acquire images and pass them to the host computer.  I then ran Vision Assistant 2012 and created a short (4 step) algorithm to apply to the images to find circles.  I can run this algorithm on the host computer in Vision Assistant and within LabVIEW on the host computer (after exporting the sub-VIs).  However, when I put that algorithm into the RT code and try to download it to the smart camera, it gives the error shown in the attached jpg.  Before adding this algorithm, the RT code downloaded fine.  The error appears to be related to just one sub-vi, the Find Circular Edge 2 VI.  Are there some vision filters and sub-VI's that cannot be loaded into RT?

Thanks,

Are you sure you have the same version of Vision installed on your host as what you have installed to your target? It looks like they are mismatched to me.

Yes, I'm relatively sure.  Although I've tried this download from two laptops, the first (and the one I used to take the screen shot) was the computer that I used to load software onto the Smart Camera.  I don't think any updates have run on that laptop since.

I don't really see any evidence of a version mismatch, based on the screen shot or anything else.  Are you suggesting that based on the symptom or past experience?  If that is the case, would it make sense that all the other VI's load OK, and it just finally gets stuck on that one VI?

  It turns out that that sub-VI is in a lvlib library.  In order to use it on the camera, I had to create a new copy of it.  You can't even use "Save As" to save it out somewhere else.

  What is the normal deployment strategy for this situation?

Thanks,
