MATLAB: Trying to get matlab mex file to work

ccppmex

I've been trying to run a c file in matlab with mex function. I have been getting this same error that's below. I cannot edit the names of the directory files because I do not have admin access. Everything was created automatically. I downloaded VS2010e as the compiler.

Hi,
seems like you are trying to compile the example file in the directory where it comes with MATLAB. Under Windows 7 or Vista the UAC blocks write access to the C:\Program Files\... folders, which results in such an error. Try to copy that file to a folder where you have write access and compile it in there.
