I downloaded the installer for PHP 4.0.4pl1 and the install works until the point where the installer would configure IIS 4.0 for PHP.  The error I received was:

IISConfig

MSCOMCTL.OCX is not correctly registered.

Once I downloaded and registered MSCOMCTL.OCX, the installer ran fine, but the installer should check for the presence of MSCOMCTL.OCX on the system.

I couldn't find any information anywhere about this, so I figured that someone should know about the problem.

Here's a rundown of my system:

NT 4.0, with SP6a.
IIS 4.0
IE 4.01 SP1

Email me if you need more specific details.
