How to I use older version dll file for new MATLAB.

I am using both Matlab 2010 and Matlab 2015b (both are 32bit). In matlab 2010, I have a library which I use a *dll file ( I give the directory into S function) and work on simulink. I want to work with same library in Matlab 2015b, library seems working, however, when I write same directory, I get and error says dll file could not be found. Is it because Matlab changed compile principles (dll to mex32/mex64 files) or can I still make it work ?

My memory is that there was a mex change in R2011a and that old versions can no longer be used. However, I am having difficulty finding the details at the moment to verify.

I think it is a bit later, as I started with R2011b and I was there during the change. I remember that I found it really annoying as you had to recompile everything for each OS type, while dll worked on every system.

So as far as I know, you can't make dlls work on later releases. I searched a ton for possible solutions, but never found one. So if you find anything, please post it here.

?? .dll would never have worked on OS-X or Linux
