R2024a Prerelease will not start due to OpenGL Startup Plugin Fatal Error

Hello.

I am trying to install the MATLAB R2024a Prerelease, and although the installation is successful, I can't open R2024a due to a Fatal Error.

The following is the text from the error:

Dynamic exception type: class cppmicroservices::SharedLibraryException std::exception::what: Loading C:\Program Files\MATLAB\R2024a\bin\matlab_starup_plugins\graphics\opengl_startup_plugin\mwopengl_startup_plugin.dll failed with error: The specified module could not be found. : not connected: not connected.

I have already confirmed that my GPU is running a version of OpenGL that surpasses the system minimums, and I uninstalled and reinstalled R2024a. The uninstaller wouldn't actually run so I just deleted the whole folder, I assume that's an unrelated problem. R2023a continues to run fine. Any guidance would be appreciated. Below are my system details:

Dell XPS 15 9570

Intel Core i7-8750H CPU @ 2.20 GHz (Turbo up to 4.1GHz)

32Gb DDR4 Ram

Windows 11 Professional

Intel UHD Graphics 630 (Running WebGL/OpenGL 4.6)

I have encountered the same problem. Have you resolved it?

Could you please tell me how to solve it？

Maybe just a file are viewed as virus and isolated from the windows defender. The solution is openning your windows denfenders and finding your records of defendence then checking if there is your file and releasing it.

I have had the same problem. I can confirm the problem seems to be with Windows Defender - you need to release the file.

[resul aydin]

i notified the Matlab support but they didnt answer yet, go to "Virus & threat protection -> protection history, then find threat about matlab and restore/remove it. It worked for me.

[jie wei]

confirmed that Andy and Resul's approach works: restore the "severe" threat by windows defender.

Is the installation straightforward?

Any video guide?

Xinyu‘s solution is useful. I have just recover the Trojan:Win32/Wacatac.B!ml , which is relative to the ddux.dll. Problem solved.

[Ronald Aarts]

Xinyu‘s solution also works for me, at least for the time being as Windows Defender insists on removing this "Trojan".

Hi,

please go to Windows Defender and restore the file "C:\Program Files\MATLAB\R2024a\bin\win64\ddux.dll". It has been falsely marked as Trojan:Win32/Malgent!MSR and quarantined.

Good Luck, Jan
