Hi, I am using the LabJack U6 and Labview program to read the signal from the device. When I run LJLogUD, it shows an error message as follow: An error occured loading VI 'Mean.vi' . LabVIEW load error code 21: An external subroutine required required for execution could not be found. Do you have an idea what is the problem? Thanks a lot, User

That means that LabVIEW can't find the sub-vi "Mean.vi". That is a standard VI provide with LabVIEW by NI, not a VI we have made. When you first load LJLogUD.vi, do you see a message where LabVIEW is searching for that VI? Where is it looking? Note that LJLogUD.vi is a pretty complex program. If you want to just run it, use LJLogUD.exe. If you want to modify and make your own program in LabVIEW, I suggest you start with a simpler example.
