MSINET.OCX dependencies

    I have a VB6 program which I sell for designing certain kinds of lathe
    projects. My development base is an XP2 machine with MSDN installed.
    Naturally, nothing fails on my machine.

    Recently I added automatic program updating to the programs features using
    the Internet Transfer Control (MSINET.OCX). MSINET.OCX is included in my
    installation process and the program works fine on XP based machines. It does
    not run on all Vista machines. On the erroring machines the message displayed
    is "Component MSINET.OCX or one of its dependencies not correctly regestered:
    a file is missing or invalid". Now I know that the component is present in
    the same folder as the application and I know that wininet.dll is also
    present on the target machines. Dependency Walker, run on my development
    machine tells me nothing of interest even in the profiling mode and I don't
    have a Vista machine to check on.

    Can anyone help

    Not a very helpful response, but I'll take a look.

    I've since revised my process to work with wininet.dll directly and I
    believe that has solved the problem. Along the way, I discovered and fixed a
    bug in the sample code provided on the MSDN library disc.

    I've also learned that if the program is started using a right click on the
    shortcut and the 'Run as Administrator' option is selected, the problem goes
    away. User class dependent registration? Interesting concept for keeping
    people away from where they don't belong but the error message received is
    not at all useful.
