@theopenem_admin originally, it hung on configuring (or installing) IIS components, but I followed the guide and already had IIS installed, so that was strange to me that it tried to install it again. I uninstalled IIS and ran the installer again, but it said it was installed and I ran a repair instead of the full install.

Want me to uninstall and reinstall? The biggest problem is that it keeps telling me the machine needs a reboot even after multiple reboots, and we can't reboot it during school hours. I had to go into the registry and remove the things that the pending reboot checks for it to install.
