Error Installing MacOS 14 on MBPRO 2017

When I use OpenCoreLegacy Patcher to download the installer it gives an error of Read Time out. When I copy the installer link and download it using any other downloader such as Free Download Manager, it gets downloaded successfully. But when I try to install it, it gives the following error

Failed to create macOS installer

Output: Started erase on disk9

Formatting disk9s2 as Mac OS Extended with name OCLP-Installer

Initialized /dev/rdisk9s2 as a 29 GB case-insensitive HFS Plus volume

Error: /var/folders/lc/0mwzq6l16zq3rfwrs_z623280000gn/T/tmpb4rh2lkv/Install macOS Sonoma.app does not appear to be a valid OS installer application.

What I have tried so far.

1. Installing and older version ov OCLP
2. Tested USB drive and its fine. Its copying files and other stuff fine.
3. Tried downloading MacOS 15 and it gives the same error

Any help will be greatly appreciated.

Thanks, alot.
