Hi Iurii,

There are a few reasons why you may be getting this error. Please try the following steps to resolve the issue.

This error typically occurs when installing a new version of MATLAB over an existing installation of a prerelease. Please try the following steps to resolve the issue.

1) Cancel the installation and remove the existing prerelease installation. Once the previous prerelease installation folder has been removed then you can start the installer again.

2) There may be an issue with the target installation directory. You will want to try installing into a new directory that did not previously exist on the system.

3) The files that you downloaded may be corrupt or incomplete. Delete all of the installation files on your system, and download your products again from your MathWorks Account.

After trying these steps, if you are still encountering this issue, please contact MathWorks support using the follow link:
