Hi,
It seems that the version of MCR that the geoPIV_RG software is looking for is MCR 8.4. This could indicate that the software was compiled using some other version of MATLAB and MATLAB Compiler. You can try installing MCR 8.4 and see if that resolves the issue.
To do this, you can download the MATLAB Compiler Runtime (MCR) 8.4 installer by navigating to the link provided below, and then install it on your system. Once the installation is complete, make sure that you add the path to the MCR 8.4 DLL files to the system PATH environment variable. You should also make sure that the geoPIV_RG software is configured to use the correct version of the MCR.

If you have installed multiple versions of the MCR on your system, you can use the "mcrversion" command in the MATLAB Command Window to check which versions are installed. If MCR 8.4 is not installed, then the software you are using may be looking for a version that is no longer available.
You can also look at this MATLAB answer which is addressing a similar issue: Why do I receive "Could not find version X.X of the MATLAB Runtime" when running my compiled app, although MATLAB R... - MATLAB Answers - MATLAB Central (mathworks.com)
If the problem persists even after installing MCR 8.4, ensure that the version of the program is compatible with the version of MATLAB Runtime that you have installed. You can check the compatibility of the program with MATLAB Runtime by consulting the documentation attached below.

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.
Sometimes the solution may also be as simple as rebooting your system :)
Hope this helps!
