During installation I get a message about "CTL3D.DLL".
This is just a quirk of the installation program. On some Windows 95/98 systems, it will give messages about CTL3D.DLL only being for NT, and on some NT systems the message will say it is only for Windows 95. Just dismiss the message and continue the installation as normal. It will not affect the installation or BulletProof Go!Zilla program peformance.
