I have tried to dowload matlab now multiple times and always it says that error. I have also tried turn off my fire wall, but same thing.

I have tried to uninstall windows and reboot whole computer, but same thing again.

It always stops 3%,4%,8% or 28%.

If possible, use your phone's hotspot instead of your original network during installation and download.

I had the same problem, I sovled it with the above method.

Hi Aleksi Mutru,

This issue can occur when attempting to install MATLAB with a poor network connection. When the installer is attempting to download files, a failure to download a file successfully will show as a retry # attempt. The installer will make several attempts to redownload each failed file, but if still unsuccessful, will display an error.

To resolve this, check that your computer has a reliable internet connection or switch to a more reliable network. If the Installer is still unable to successfully connect, perform an offline installation.

Also try one or more of the following steps to resolve the issue:

This error can be caused by an anti-virus or security program interfering with the MATLAB installer. Disable any anti-virus you have running, and then rerun the installer.
There may be an issue with the target installation directory. Rerun the installer and specify a new directory that did not previously exist on the system.

Note: Remove the folder in the following path as well: C:\Users\<username>\AppData\Local\MathWorks\MATLAB\R20XXx
