I'm unable to open my Matlab program (version 2017A, Windows 10 Home OS). I'm getting an error message while starting Matlab from Microsoft Visual C++ Runtime library:
Assertion Failed!
Program: C:\Program
Files\MATLAB\R2017A\bin\win64\libmwfl.dll
File: b:\matlab\src\mvm\detail\mvmlocalboundmethods.cpp
Line: 114
Expression: Failed to open local mvm library: A dynamic link library (DLL) initialization routine failed.
Function: void__cdecl
mvm::detatil::MvmLocalBoundMethods::initMethods(constbool)
For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts
(Press Retry to debug the application - JIT must be enabled)
Please help me with this issue.
Thank you,

The same as you. My version is 2024a. At the beginning, it is normal. However, now it displays the error message. Before that, I have tried 2019a and 2018b also has the same error

The story was that some of the installation files were corrupt. Probably, some security feature of our quite restrictive network (automotive industry) modified some dll's.
The issue was fixed by downloading an iso file of installation DVD and installing MATLAB using it.

I agree that it might be problem with installation files. In my case some files were not downloaded at all. Check file mw_download_error.log in your %temp% directory.
I fixed it by downloading the files on computer with different antivirus software. Then I copied the downloaded files from the %temp% directory to the installation source.

I met the same problem and solved it successfully!
I found that this file (libmwfl.dll)was deleted by anti-virus software. After it was recovered, MATLAB(2020a and 2023a) can be opened.
Hope my answer might help you!
