Load Error Code 21

[esa_paranoid]

Hi, I am trying to install a .exe file created using Labview 7.0
I created the file on a Windows 2000 Platform. I am trying to install it onto an XP Platform system.

The installer runs fine and installs the program. However, when I try to run the program I get the following messages:

nilvaiu.dll cannot be found.
DAQmx Write (Digital Bool 1Line 1Point).vi cannout be found.
DAQmx Read (Digital Bool 1Line 1Point).vi cannout be found.
DAQmx Read (Analog 1D DBL 1Chan NSamp).vi cannout be found.

I also get:

LabVIEW load error code 21: An external subroutine required for execution could not be found.


If anyone can help me that would be great, this is getting frustrating.

I tried to manually load "nilvaiu.dll" onto the PC...this worked but then it asked for nimdbgu.dll, loaded that, it asked for NIPALU.dll, loaded that, it asked for nipalut.dll..........

I could be here all day loading .dlls!


Thanks in advance!

hi ryan

That error code usually means that external code has not been loaded on the deployment machine.  In Ryan's case I believe that it was caused by not installing the DAQ drivers.  Make sure that you install any drivers (DAQ, VISA) and include any support for 3D Graphs or DataSocket if you are using them.  Here is a KB that goes through some of these issues.

Dear Andy

thanks a lot for the reply

but why shd i require to load the driver files onto my target machine yes it did work but the question when i making an EXE it should get attached automatically.

Please explain the need to load driver files

Hardware device drivers (DAQ, GPIB, USB, video, printers, etc.) are never part of an exe. They must be installed separately. When you create an installer, you can optionally add additional programs such as the DAQmx install but it does not do so automatically. LabVIEW 8 makes the creation of an install CD with all drivers much easier.

Hi Dennis

Thanks for the quick reply.Well so u mean to say if i try adding the DAQmx installer along with the program installer then i may get a solution to my problem.

When i load the device driver what do i do to install only DAQ card drivers and not all the device drivers.

I have Labview 7.1 PDS and we may get the upgrade soon

Also what if i use only the new DAQmx 8 with the earlier program will it work??

Thanks in advance

There's a KnowledgeBase article here on including other installers.
