cannot open .dll file in MAtlab 2012

Hi,

I have two .dll files that has been written in matlab 7.0.4 do I have to install the 7.0.4 version to view the files in matlab 2012?

Thanks, Sharmi

How are the DLLs loaded or run in MATLAB 7.0.4? I'm asking because DLLs could either be MEX-files (they are executed like any other MATLAB function), or generic DLLs (they are loaded using LOADLIBRARY).
