INCA Matlab Interface setup problems

Thanks in advance, any comments will be appreciate! The question is below: When I setup INCAMatlabInterface program, it point out "An I/O Error occured while instaling a file. this usually caused by a bad installation media or a corrupt installation file. abbort/retry" The INCA version is 5.4.0 and the Matlab version is matlab7.0 . What should I do next?
