I probably should have mentioned that someone informed me on how to
enable and use compatibility mode in Windows 2000, something I was
entirely unaware of because I never see it discussed anywhere except
here.

Using the compatibility mode method, it installed fine.

For reference:

] Search "Windows 2000 Compatiblity Mode" on google or
] run command "regsvr32 %systemroot%\apppatch\slayerui.dll", which
] activates Compatiblity mode of Windows 2000.
]
] For some reason, Windows 2000 has no UI which activates this
compatiblity
] mode, but WIndows 2000 have had numerous compatibility updates.

Note, that only an Administrator account can actually set a
compatibility mode for any shortcut to an exe, which is annoying when
you aren't using an Administrator account.

Thank you anyways, though.  It's actually a good piece of information.
