I made an application using imaq toolbox. Then I compiled it for 64bit and 32bit systems and tested it. The application worked good for the 64bit system. Whereas on the 32bit system I got an error saying and imaq function can not be found. Here's some code, where I try to find the right camera and open the camera:

deviceID = [];
imaqreset;
info = imaqhwinfo('winvideo');
devnumb = numel(info.DeviceIDs); %get number of available devices
for i=1:devnumb
    if ~isempty(strfind(info.DeviceInfo(i).DeviceName,'UI224xSE-M'))    %%find my camera
        deviceID = info.DeviceInfo(i).DeviceID;
    end
end
if ~isempty(deviceID)
    vidH = videoinput('winvideo', deviceID, 'RGB32_1280x1024'); %create video object
.... %continue with initialization of video object
end

When I try to run the .exe file I get 'Undefined function or variable 'imaqreset'.'

I can also assure, that I have installed the imaq toolbox, because it works on 64bit but also by typing

   >>ver
MATLAB                                                Version 8.3        (R2014a)
Image Acquisition Toolbox                             Version 4.7        (R2014a)
Image Processing Toolbox                              Version 9.0        (R2014a)
MATLAB Builder JA                                     Version 2.3.1      (R2014a)
MATLAB Compiler                                       Version 5.1        (R2014a)

Next I tried to comment out the line with imaqreset, because it is not really necessary but the i got the same error saying there is no defined function imaqhwinfo.

So why does my application work on 64bit systems but not on 32bit?
