When installing MATLAB I get the error above at 0% in the installer. The error additionally suggest looking at the installation log. The installation log has the following error:

The issue is likely related to old cached files in the MathWorks folder in Downloads. Removing this folder will allow the installation to continue.

I recommend you contact Technical Support directly using the Contact Us link in the upper-right corner of this page. They can work with you to determine why you're still experiencing this problem and how to correct or avoid it.
