MATLAB: Could not find MATLAB runtime but redownloading without changing path fixed the issue – need new fix due to admin rights

compilerMATLABMATLAB Compilermatlab guiruntime

I have created and compiled a user interface. The installer contains the correct matlab runtime (9.2) automatically.

Some users get this error (notably not all):

Could not find version 9.2 of the MATLAB Runtime. Attempting to load mclmcrrt9_2.dll Please install the correct version of the MATLAB Runtime. Contact your vendor if you do not have an installer for the MATLAB Runtime.

Not all users have received this error. Most advice suggests changing a path in system files, so downloading 9.2 from the MathWorks site and overwriting the copy from the compiler should not have had any effect – yet it fixed the problem on one computer. On the others admin rights are required to download runtime, so it cannot be re-downloaded. Runtime is already present on the computers.

How should I direct users to proceed? Can they change a system path once it is downloaded onto their computer? Or is this due to some form of corrupted data from the download?

Just restart their computer, it magically finds it.

MATLAB: Where is the MATLAB Compiler Runtime (MCR) Installer located

As of R2012a, the MATLAB Compiler Runtime (MCR) can be retrieved from our website from the MATLAB Compiler page:

http://www.mathworks.com/products/compiler/mcr/index.html

For releases R2017b and earlier, see below:

The MATLAB Compiler Runtime (MCR) installer must be retrieved from a computer that has MATLAB and MATLAB Compiler installed. The location of the MATLAB Compiler Runtime (MCR) installer depends on the operating system of the computer. You can find the location of the MATLAB Compiler Runtime (MCR) installer by running the below in MATLAB:

mcrinstaller

Please see below for some example paths:

Windows:

$MATLAB\toolbox\compiler\deploy\win32|64\MCRInstaller.exe

Mac OS X:

$MATLAB/toolbox/compiler/deploy/maci32|64/MCRInstaller.zip

Unix/Linux:

$MATLAB/toolbox/compiler/deploy/glnx86|a64/MCRInstaller.bin

(where $MATLAB is the location of your MATLAB installation directory or installation media)

As of 2018a, the standalone MCRInstaller executable does not ship with the MATLAB Compiler™ product.

When you package a MATLAB function using the Application Compiler or Library Compiler apps and select the option Runtime included in package, you are prompted to download the MATLAB Runtime installer. Once you accept, the MATLAB Runtime installer is downloaded and packaged with the application.

If you do not have internet access, you need to download the MATLAB Runtime installer from a computer that is connected to the Internet. After downloading the MATLAB Runtime installer, you will need to transfer the installer to the computer that is not connected to the Internet.

MATLAB: Where is the file MCRInstaller.exe located on the machine

In MATLAB 7.5 (R2007b) and newer, the following command can be used to determine where the installer is located:

mcrinstaller

For older versions of MATLAB, the MCRInstaller.exe is located in the folder:

 $MATLABROOT\toolbox\compiler\deploy\$ARCH

where $MATLABROOT is the MATLAB root directory and $ARCH is the system architecture (such as win32, win64, glnx86 etc.). The MATLAB root directory may be determined by entering the command:

matlabroot

at the MATLAB command prompt.
