Hello Shubham,

The error message provided typically indicates a problem with the installation process for MATLAB or Simulink, often related to network issues or server connectivity problems. Here are several steps to troubleshoot and resolve this issue:

1. Check Network Connection: Ensure that the internet connection is stable and working correctly.
2. Disable Firewall and Antivirus Temporarily: Sometimes, firewall or antivirus software might block the communication with MathWorks servers. Temporarily disable these security features and try running the setup again.
3. Run the Installer as Administrator: Running the installer with administrative privileges can sometimes resolve permissions-related issues. Right-click on "setup.exe" and select Run as administrator.
4. Use a Different Network: If possible, try using a different network connection. For example, if on a corporate network, switch to a home network or a mobile hotspot.
5. Download the Installer Again: The installer file might be corrupted. Download a fresh copy of the installer from the MathWorks website. Consider going over the FAQ page.
6. Check Proxy Settings: If working behind a proxy server, make sure that the proxy settings are correctly configured in your system. Navigate to Control Panel > Internet Options > Connections tab > LAN settings and ensure that the proxy settings are correctly configured.
7. Use the Offline Installer: If the online installer continues to fail, the offline installer can be used. This method does not require constant internet access during the installation process. It is present in the downloads section in MathWorks website.

Hope this helps!
