I downloaded Fedora Media Writer from https://getfedora.org/en/workstation/download/ by clicking on the Windows icon, which links to https://getfedora.org/fmw/FedoraMediaWriter-win32-latest.exe. After downloading it, I ran that file, which installed Fedora Media Writer (mediawriter.exe). But then running Fedora Media Writer itself resulted in an error message. The titlebar of the dialog box said, “mediawriter.exe - Entry Point Not Found”, and the text inside said, “The procedure entry point CreateEventW could not be located in the dynamic link library api-ms-win-core-synch-l1-2-0.dll.”

Almost any burner is usually capable of directly writing an iso to a device. I have not used windows 7 so do not know what is available there.
A quick search for ‘how to write an iso to usb windows 7’ gave this as the first hit. https://neosmart.net/wiki/bootable-windows-usb/ which links to this “Easy USB Creator 2.0 by NeoSmart”.
Usually we recommend using rufus or etcher for the purpose.
