Stand-alone from Simulink with avt cameras doesn't build

I'm trying to compile a simulink model using rsim to make a stand-alone with a camera Stingray F-080C from AVT. I'm using the AVTMatlab Adaptor from the AVT website. My model simply captures the video and save it in a .AVI file, using the imaq block and the "To Multimedia file" block. I use the next commands to build the stand-alone model:

mdlName = 'cam';
open_system(mdlName);
cs = getActiveConfigSet(mdlName);
cs.switchTarget('rsim.tlc',[]);
rtwbuild(mdlName);

When I use my webcam the process is successful but when I use the AVT camera I got the next warnings and error:

### Starting build procedure for model: CAM

Does anyone how to solve this problem? I really need to compile this model because I need to run this every 30 minutes during a couple of months.
