Standalone exe could not find 9.8 runtime in win7 even it's installed already. But this won't happen on win10.

I tried to run a standalone matlab exe on a win7 x64 workstation. I used the 'MyAppInstaller_mcr.exe' installer in 'for_redistribution' folder to install the runtime, and create a corresponding environment variable according to https://www.mathworks.com/help/compiler_sdk/cxx/mcr-path-settings-for-run-time-deployment.html#btnytqp-5. However, when I click the installed application it just keep saying 'Could not find version 9.8 of the MATLAB Runtime.Attempting to load mclmcrrt9_8.dll.Please install the correct version of the MATLAB Runtime.' I can even find the 'mclmcrrt9_8.dll' file in ‘...\Matlab Runtime\v98\win64’, but the application can't.

The same installation is done on another workstation with win10 and everything works well, where even the environment variable is not specially created. I wonder how to solve this problem in the win7 system. The install package should be created with MATLAB 2020a in a win10 PC.
