IMAQ Find Edge 2 was not found

[EthanHenry]

Hey y'all,

          I recently installed the NI Vision Development Module, and while playing around with it, noticed that a friends code wouldn't run.  After checking the errors, I found that I didn't have IMAQ Find Edge 2, only IMAQ Find Edge.  I've tried repairing the NI Vision Development Module, to no avail.  Is there something I'm missing?  I'm currently using LabVIEW 2018.  Thanks!

I'm not sure, but I suspect, at some point, NI substituted a different algorithm, possibly with different behavior and possibly different connections.  Curiously, when I did a Web search for Find Edge vs Find Edge 2, I found a recent NI description of the Vision routines that listed both Find Edge and Find Edge 2.  I've seen "Version 2" code pop up in the Vision routines, where it signified a change in implementation and "features".

Can you check which version of LabVIEW your friend is running?  It is probably not LabVIEW 2018 ...

I figured it out, and you were partially correct.  After talking with him, I realized that, while he was using LabVIEW 2018, he was using Vision 2019.  I installed that, and after restarting I have it now.  Thanks for the help!
