can anyone help me with installing postgresql in win2k?

I've extracted cygwin and cygipc. After extracting cygipc I can't run this command. I'm using ms-dos prompt.

ipc-daemon --install-as-service

from the cypipc documentation it said: Remember, if you are calling ipc-daemon from a `naked' dosbox, you'll need to use the `2>&1 | cat' workaround in order to see the output of the above commands -- see the W9X discussion above.

ok I run the command like this:
ipc-daemon --install-as-service 2>&1 | cat
and then nothing happen. just another dos prompt came up.

am I missing something? can someone explain it line by line what to do? i'm new to postgresql
