Error: Could not find version 9.6 of the MATLAB Runtime. Attempting to load mclmcrrt9_6.dll.

see https://uk.mathworks.com/matlabcentral/answers/343074-why-do-i-receive-could-not-find-version-x-x-of-the-matlab-runtime-when-running-my-compiled-app-al

I had 3 versions, 8.5, 9.6, 9.12 installed. When I tried to run a program dependent on 9.6, I got the error message. I deleted every Matlab version using using IOBit Uninstall. I searched the Registry and found no reference to Matlab.

I reinstalled Matlab runtime 9.6 on C:\Program Files\MATLAB\MATLAB Runtime\v96, and checked the Path- it was present.

Ran the program, and got the same error message.

What more can I do?

Hi Horie,

Make sure that the version of the program is compatible with the version of MATLAB Runtime that you have installed. If the program was compiled using MATLAB R2020a, for example, it will not be compatible with MATLAB Runtime 9.6. You can check the compatibility of the program with MATLAB Runtime by consulting the documentation attached below.

Link to MATLAB runtime documentation: https://www.mathworks.com/products/compiler/matlab-runtime.html

If the problem persists, there is a possibility that there is an issue with the installation of the program itself. Try uninstalling the program completely, then reinstalling it and ensuring you select the correct MATLAB Runtime version path.

You can also look at this MATLAB answer for more understanding on why this may be happening: https://www.mathworks.com/matlabcentral/answers/1896450-i-receive-could-not-find-version-9-11of-the-matlab-runtime-when-running-my-compiled-app-my-matla

Hope this helps!

Thank you.

I found in a previous post that rebooting the computer might hlep solve the problem. And in my case it seems to have done. Presumably something remains running from the first version that interferes with the recognition of the next version.
