The installer proceeds as expected only with the prefix set to Windows 10;
setting the prefix to Windows 7 claims you need two Windows 7 hotfixes
installed and forces you to close the program.

However, when you do proceed to the installation in Windows 10 mode, it claims
that not enough storage is present to install even if there is more than enough
storage space present.
