U12 under LabVIEW 2013

I am looking for a list of working examples for my U12. I have LabVIEW 2013 (32 bit) installed and have copied the examples from both the driver installable for Windows and the files from LabVIEW71_LJU12.zip (for LV9+) to the LabVIEW ADDON directory. All of these appear in the menu under the block diagram panel so I can select any from there. 

However, although some of these examples do run, many fail to with "Sub vi is not executable" errors. Do you have a full example list that is compatible with my version of LabVIEW 2013?

All examples should work. 

All examples should work.  What is wrong with the sub-vi that is not executable?

While some functions do work

While some functions do work (like the simple example vi), I get this "The subVI is not executable. You must fix all errors in the subVI before this VI can run." error when running others like the periodic pulse output function:

Selecting to view the error shows me the block diagram with the LJpulse box highlighted:

And I don't know what else to do from there.

I forgot to add that I had to

I forgot to add that I had to copy in an ljackuw.dll file downloaded from the net because the program requested it at runtime but it was not found on my machine - not part of the install?

I also noticed that the newer example folders (LV9+) come with a file with the same name but it has a .lib extension instead.

Now open that sub-vi and see what is wrong with it.  Keep drilling down until you find the actual error.

I suggest you delete whatever you manually copied as the U12 installer should definitely have installed ljackuw.dll.  Go to your root C: drive and search from there to find it.

Try running ljtest.exe or ljlogger.exe.  If they work you know that ljackuw.dll is on your machine as they need it.


I also noticed that the newer example folders (LV9+) come with a file with the same name but it has a .lib extension instead.

I'm not sure why those LabVIEW archives would include ljackuw.lib as I can't think of a time or reason when LabVIEW would use that.  The important file in the LabVIEW archives is ljackuw.llb, as that is the labview library of U12 function call VIs.
