Fix "Press any key" on Microsoft Windows
Fix "Press any key" on Microsoft Windows

`getch` throws a `Errno::EBADF: Bad file descriptor` error on Microsoft
Windows. I am unable to fix that. Using `getc` creates the same behavior
and also works on Microsoft Windows.

This fixes the "Press any key" prompts on Microsoft's OS, fixing the
installer prompts.
