Cannot install the pre-release file.

So I have download matlab however could not installed the file as it is not verified. So what should I do?

If you are on macOS, try right clicking on the installer and selecting 'Open'. You may potentially then be able to bypass the verification.

If that doesn't work, can you please provide more details about the operating system and take a screenshot of the error?

Hi Christina,

I understand that you are facing difficulty installing MATLAB because the file is not verified, this could be due to operating system's security settings or a problem with the download itself. Here are few workarounds to resolve the issue:

• Ensure to have downloaded the MATLAB installer directly from the official MathWorks website. Downloading from unofficial sources can be risky and might lead to such verification issues.
• Check the File Integrity by checking its checksum against the one provided on the MathWorks website. If the checksums do not match, the file may be corrupted, and should download it again.
• Operating System Security Settings:

1. Windows: One might see a warning from Windows Defender or another security programs. Proceed by clicking "More info" or a similar option and then choosing "Run anyway."
2. macOS: If Mac is preventing the installation because the app is not from the App Store or identified developers, override this by going to the "Security & Privacy" settings in "System Preferences." Click "Open Anyway" next to the message about MATLAB being blocked.
3. Linux: Ensure to have the necessary permissions to execute the installer. One might need to make the file executable by running “chmod +x /path/to/matlab_installer_file” in the terminal.
4. Run as Administrator or with Sudo: On Windows, right-click the installer and select "Run as administrator." On macOS or Linux, can open a terminal and run the installer with Sudo to ensure having the necessary permissions.

• Disable Antivirus Temporarily as sometimes, antivirus software can incorrectly flag legitimate installers as suspicious. If source of the installer is trustworthy, temporarily disable antivirus software during the installation process. Remember to re-enable it immediately after.
• Ensure the operating system is up to date. Sometimes, compatibility issues can be resolved with the latest updates.

If still unable to install MATLAB, contact MathWorks support for assistance.

Always be cautious when overriding security settings and ensure that you trust the source of the software being installed.
