Matlab don't work

I'm on a Windows 11 PRO. I had a well functioning Matlab 2023b installed on 11 Home and I upgraded to 11 Pro then it stopped working. When I try to open Matlab, it shows up in my Task Manager but the software just doesn't open.

I uninstalled 2023b,and installed and activated it, but it still shows the same behavior.

Can someone please help me? I've wasted hours of effort on this and can't make it work.

Thanks

Hi Tonciu, 

I understand that you are facing difficulty in starting MATLAB after upgrading the operating system from Windows 11 Home to Windows 11 Pro.

When MATLAB fails to open but shows up in the Task Manager, it is typically due to a problem with the MATLAB configuration or a conflict with other software or system settings on your computer. Here are steps one can try to resolve the issue:

• Run as Administrator: Right-click on the MATLAB shortcut and select "Run as administrator" to see if it is a permissions issue.
• Compatibility Mode: Right-click on the MATLAB shortcut, select "Properties," go to the "Compatibility" tab, and try running MATLAB in compatibility mode for an earlier version of Windows.
• Reset MATLAB Preferences: Sometimes MATLAB preferences can become corrupted. Reset MATLAB to the default settings by renaming or deleting the preferences directory. The preferences directory is typically located at:

C:\Users\<YourUserName>\AppData\Roaming\MathWorks\MATLAB\<MATLAB_Version> 

Rename or delete this folder, and then try starting MATLAB again.

• Check for Error Logs: Check for error logs in the MATLAB preferences directory or the MATLAB installation directory. These logs might provide clues to what is going wrong.
• Disable Startup Options: Try starting MATLAB with no desktop by running “matlab -nodesktop” from the Command Prompt to see if the problem is with the desktop environment.
• Reinstall Graphics Driver: Since MATLAB uses hardware-accelerated graphics, there could be an issue with your graphics driver. Try updating or reinstalling your graphics driver.
• Disable Third-Party Services and Startup Programs: A third-party service or program might be causing a conflict. You can perform a clean boot by disabling all non-Microsoft services and startup programs and then try to start MATLAB.
• Press “Win + R”, type “msconfig”, and press Enter.
• Go to the "Services" tab, check "Hide all Microsoft services," and then click "Disable all."
• Go to the "Startup" tab, click "Open Task Manager," and disable all startup items.
• Restart your computer and try opening MATLAB.

Remember to back up your MATLAB files and custom configurations before making any significant changes to your system or MATLAB installation.

Hope it helps! 

Best Regards,
