I'm compiling with lcc-win32 2.4.1 on w10 64bit platform in 32bit Matlab, why is my program not working on w7 target machine with compatible MCR?

I'm running windows10 on a 64bit platform.

I downloaded the 32bit v. of R2012a Matlab in order to get the included lcc-win32 2.4.1 compiler.

From this question thread, https://www.mathworks.com/matlabcentral/answers/143754-64-bit-32-bit-compatible-standalone-app

I have reason to believe that my compiled programs will be compatible with 32 and 64bit target systems, provided they have the necessary MCRs.

My target system is windows7, 64bit, with the R2012a MCRs for 32 and 64bit installed.

I attached a photo of the problem details, when the .exe stops working...

BONUS Question: Will there be any foreseeable issues downloading the MCR for compatibility with newer matlab versions on a windows7 environment? or Rather, is it generally recommended to use matlab versions in the era of w7 when target systems are running w7?

It is not clear to me why you would specifically want lcc-win32 ? As opposed to, say, SDK 7.1 ? Not that SDK 7.1 is easy to install on Windows 10, but it can be done apparently.

I successfully downloaded SDK 7.1 on my platform, however, my target system didn't like my .exe still failed with this message "Locale initialization failed in opcore with status code:1"

I took it to mean that I was missing some C++ Visual studio redist.

I've been trying to make this work, without messing with .DLL files on the target system...

I'm trying to avoid touching .DLL files on the target system, so I was hoping I could get away with using the lcc-win32
