Why can't my program find the correct MCR to use?

I have MCR(7.14-R2011B) installed on my computer. I recently installed R2012b that uses MCR(7.16). I built an executable for both MCR's and deployed each executable. When I run on the target computer it cannot find the correct MCR for the R2012b executable.

Run the program from a OS command console window, so any error message don't vanish. Then tell us what it says. It will say that some MCR does not exist and it will give you the path. Make sure that the path is absolutely there. If you have Windows, go into control panel / programs and features, and look for it. Tell me what version(s) appear in Control Panel.
