Hi Singam,

Looks like the error message you're seeing is indicating that you do not have write permissions to the specified folder. This is a common issue that can occur if the user account you're using doesnt have the necessary permissions to write to the directory where MATLAB is trying to install the toolbox.

Here are some steps you can follow to resolve this issue:

1. Check the following MATLAB Answer post to know about the 'Something Unexpected Occurred when installing MathWorks Products': (https://www.mathworks.com/matlabcentral/answers/489806-why-do-i-see-the-error-something-unexpected-occurred-when-installing-mathworks-products#:~:text=This%20error%20may%20be%20caused,reattempt%20the%20installation%20once%20more)
2. Run as Administrator: If you’re on a Windows system, try running the MATLAB installer as an administrator. You can do this by right-clicking on the installer and selecting ‘Run as administrator’.
3. Check Folder Permissions: Ensure that you have write permissions for the folder where MATLAB is trying to install the toolbox. You can check this by right-clicking on the folder, selecting ‘Properties’, and then navigating to the ‘Security’ tab. If you do not have write permissions, you will need to modify the permissions or choose a different install location.
4. Choose a Different Install Location: If you’re unable to modify the folder permissions, you could try installing the toolbox to a different location where you do have write permissions. (https://www.mathworks.com/help/install/ug/install-using-a-file-installation-key.html)

What if you do have writes to the folder and it continues to give this error code?

Then you can try these:

• Try running MATLAB as an administrator, even if you already have admin rights. Right-click on the MATLAB application and select "Run as administrator".
• Restart your computer and try the installation again. Sometimes temporary files or processes can cause permission issues that are resolved by a restart.
• Check if your antivirus or firewall software is blocking MATLAB from writing to the folder. Try temporarily disabling them and attempt the installation again.
• Clear cache
