I'm very new to this as well. I tried to install Apache 2.0.43 on
Windows XP and ran into many of the same problems as original poster,
but even worse. Upon initially starting Apache, I too received the
prompt screen, which wouldn't accept any input. I closed this screen
and checked my httpd.conf file and changed it from 127.0.0.1 to
localhost. Now when I attempt to start Apache the prompt window
briefly opens before immediately closing again (so quickly I can
barely see it). I even tried to uninstall and reinstall, but it seems
to have maintained the old httpd.conf file.

What am I doing wrong? And how do I find the Windows host file?

I appreciate any help offered.

Thanks.
