Program doesn't detect library

[77maxmustermann]

So I have a program that I'm trying the first time I used it when I accidentally clicked ignore when he was searching for the library any way to get the program that searchs for the Sub VIs and Library location to pop up again?

Here is a screenshot

Hi Max,

close all without saving.

Exit LabVIEW.

Start LabVIEW again.

Load your project and the mainVI…

Sadly it didn't work I don't get it

this program worked perfectly fine on two others computers one was using labciew 2016 the other 2018 (and this one 2018 as well)

Hi Max,

checkout an older version of the VI(s) from your SCC system.

You don't use any SCC (source code control) so far? Lesson learned: use SCC!

I dont really need to this is a VI provided from a company to use on of their Instruments. It didnt get any modification

Hi Max,

when there is no modification to the VI(s) then LabVIEW will try to load that DLL (after the next restart) again!

Yeah tried  that the problem seems to be something else. It appears my theory was wrong the reason is that the program actually already found the dll. The problem seems to be the dll: The other computers work labview are 32 bits version, this one is 64 bits. could that be the problem?

I guess you talk about LabVIEW-32bit vs. LabVIEW-64bit versions: then the answer is YES!

You need to use the same bitness for LabVIEW and your DLL…

Nice we're getting closer and closer like in a saturday morning detective cartoon !

Any idea how to fix it though? how is it possible the change the DLLs "bitness"?

[GerdW]

Hi Max,

there are two options:

1. Get the source code of that DLL (and the same compiler) and compile the DLL for the needed bitness. (I'm no expert in compiling C code.)

2. Install LabVIEW-32bit and use the current DLL.

Which option is easier for you?
