Imagemagick command conflict on Windows

[MUmarShahbaz]

Error

Imagemagick is not installed even though it is.

Likely cause

Imagemagick detection uses the convert command

      # Returns an array of formats that imagemagick can handle.
      def magick_formats
        if command?('convert')
          @magick_formats ||= `convert -version`
                              .scan(/Delegates.*/)
                              .first
                              .delete_prefix('Delegates (built-in):')
                              .split
        else
          @magick_formats = []
        end
      end

Reason

The command convert conflicts with the windows file system utility convert. The command magick is more suitable.
