MCR: Running a 32-Bit executable on a 64-Bit system

I am using Windows 7 64-Bit and i tried to run a 32-Bit executable (EXE) on it. After some back and forth installing the MATLAB Compiler Runtimes (MCR) I found out, that I have to install the 64-Bit MCR AND the 32-Bit MCR on the machine to make it work. (I only tried it in the order 64-Bit first, then 32-Bit. Maybe it works the other way round, too?) This approach seems complicated to me. If I only install the 64-Bit MCR and try to run the 32-Bit EXE, an error message tells me about wrong dlls. Is it planned to include the missing functionality (= run 32-Bit EXE with 64-Bit MCR) in later MATLAB releases?

According to this solution, you only need to install 32-bit MCR to run a 32-bit executable in emulation mode. Where did you find the information that you also need the 64-bit MCR?

Hm, right. On a second PC I infact only needed to install the 32-bit MCR to run a 32-bit executable. Thanks!
