  • Try to install with Bootable media. Not through 32bit Windows

You can't upgrade from a 32-bit edition to a 64-bit edition of Windows. You have to do a clean install. You need to backup your data, boot the computer from the installation medium and choose a clean install.

You can't upgrade to a 64-bit OS on a system with a 32-bit OS, you have to do a full install.

It looks like you're trying to upgrade an installed 32 bit Windows (7, 8 or 8.1) to a 64 bit Windows 10.

You can either uninstall the old Windows version (or format the disk partition it's installed on, erasing all the data on it) or install Windows 10 side-by-side in a new partition.
