Hi @megha pawar

This issue appears to be related to the installation of a Support Package. It may be caused by security software or firewalls blocking access to the Support Package server. To resolve this, perform a clean re-installation and opt for an offline installation.

Here is how you can do it:

1. Uninstall and Remove Residual Files:

a. In MATLAB, go to "Add-ons" > "Manage Add-ons", find the Support Package, and uninstall it. Then close MATLAB.

b. Delete residual files from the following locations:

• C:\ProgramData\MATLAB\SupportPackages\R20XXx\
• \Downloads\MathWorks\SupportPackages\R20XXx\.

(replace R20XXx with your MATLAB version, e.g., R2023a).

If "ProgramData" is hidden, use "%ProgramData%" in Windows Search to access it.

2. Download and Install Offline:

a. Download the "Support Software Downloader" from here: https://www.mathworks.com/support/install/support-software-downloader.html

b. Run the downloader, log into your MathWorks account, and download the required Support Package.

c. Follow the instructions in the included readme text file to complete the offline installation.
