Problem while installing Lilypond

[Ankush Laxman]

Hi,

I use a 64-bit Windows 10 machine. I downloaded the latest version of the
Lilypond installation file for Windows from the Lilypond website (
http://lilypond.org/windows.html). When I try to compile the test.ly file
from the command line, I get the following error:

GNU LilyPond 2.18.2
Processing `test.ly'
Parsing...
error: program too old: 2.18.2 (file requires: 2.22.0)
Interpreting music...
Preprocessing graphical objects...terminate called after throwing an
instance of 'std::bad_alloc'
  what():  std::bad_alloc

What should I do?

Thanks,
Ankush
