This is somewhat more of an FYI than a question. However, there are a number of answers around regarding 32Bit applications that are out of date and may have people running around trying for a solution (as I just have) so I thought I'd place the info here for others to find.
I have just got off the phone from tech support regarding deploying 32bit applications from 64Bit machines and the upshot of it is:
1. The latest version of 32Bit Matlab is, and will remain, 2015b.
2. The only work around to compile 32bit applications is to install 32Bit Matlab.
3. Software written using Matlab functionality after 2015b cannot be compiled to 32Bit. No workaround, no options, no solution. 32Bit is gone.
So if you want to write 32Bit applications, use 2015b. Or, use another language. Unfortunately, changing coding environment could be my only option for my next project which is a damned shame. I love Matlab, primarily because my job is rapid development. My solutions are tested in the field, where older 32Bit machines are common, before they are re-written by others for speed and optimisation.
Disappointed to say the least.
