Why doesnt deployed .exe application recognize NI as a vendor when using DAQ toolbox?

I am trying to deploy a standalone application which uses the DAQ toolbox and session-based interface. The compiled program thows an exception on the line:

handles.s = daq.createSession('ni');

with the error message:

The vendor 'ni' is not known. Use 'daq.getVendors()' for a list of vendors.

The application runs fine in Matlab, but will not with MCR.

I have tried running as administrator, as I have read to be one solution, but it did not work for me. I also tried registering the mwnidaq.dll with regsvr32 in the command prompt, as I found that to be another possible solution. However, trying this also yielded an error (The module 'mwnidaq.dll' failed to load./~/The specified module could not be found). The dll file was in three different locations buried in the AppData folder (none of which were in a folder ending in _mcr). I tried all three without success.

I should also mention that the application does not run on the machine on which it was developed nor the deployed machine.

I am using MATLAB R2012b and the program was compiled using the built-in app from the APPS ribbon menu.

You might need to install NI drivers on the target device.

NI drivers are installed and are working properly on both the development and deployed machines.

The program works fine on the development machine when running Matlab, just not with MCR.

I get the same error on both machines.

note: I had to change the extension of the attachment to .zip and extract the mcc.enc file manually due to administrative/privilege restrictions.

I have encountered this problem using Matlab2015a. Should I try this work around also?

Hi, I have same problem in 2015 a vai matlab editor, daq works perfect but via exe file The vendor 'ni' is not known do you find any solution for that?
