Why do I get a "could not find version 7.14 of the MCR..." error when running my compiled compiled .exe?

Wrote a simple .m file to try MATLAB compiler (come with MATLAB R2010b).

After build and package, all are put into one single folder (on my computer), which contains sub-folder v714. Yet when double clicked the .exe file, got the error "could not find version 7.14 of the MCR...".

Why?

Have you run MCRInstaller.exe?

There are really 2 things that need to happen to run an application created by the MATLAB compiler.

The files for the MCR need to be in place
The system path variable needs to point to those files.

The mcrinstaller command can be used from the MATLAB command line to find the mcrinstaller.exe binary. For example:

>> mcrinstaller
The WIN64 MCR Installer, version 7.14, is:
  C:\Program Files\MATLAB\R2010b\toolbox\compiler\deploy\win64\MCRInstaller.exe
MCR installers for other platforms are located in:
  C:\Program Files\MATLAB\R2010b\toolbox\compiler\deploy\<ARCH>
<ARCH> is the value of COMPUTER('arch') on the target machine.

It is also possible to test your application against your MATLAB install if the MATLAB Compiler is also installed. You can do this from the MATLAB command line like:

>>!myexe.exe

Or from a CMD shell as long as the PATH contains the runtime directory from your MATLAB install like:

 C:\work\myexe>set PATH=C:\Program Files\MATLAB\R2010b\runtime\win64
 C:\work\myexe>myexe
 hello
 C:\work\myexe>

You need to delete mclmcrrt7_14.dll from that folder. That will definitely cause you problems. That library loads a number of others from a relative path. Those libraries won't be resolved if you move it out of runtime/win32 or runtime/win64
