Problem installing MacOs Ventura

Hello, I have a problem installing macOs Ventura on a macbook that does not support it. I am using OpenCoreLegacyPatcher, I have followed all the steps in the right way. When Ventura starts installing, I get that the installer (which I downloaded from OpenCore) is corrupted, I should download it again and try again. I've already done the entire process twice and the same thing keeps appearing. Is there any solution? I mention that I have a MacBook Pro Retina, 13 inches, early 2013, with Intel i5 and 8GB of RAM. I am installing it from a 32 GB bootable USB, 3.2 and the version of macOS it has is macOS Sierra. I also mention that in the assets section in opencore legacy it doesn't load anything, I had to download the file from Windows and upload it to Google Drive and then open it on the Macbook and download it from there, I don't know if that affects anything.
