install over mscomctl.ocx?

[greg]

hello,
we have a custom install we built for our application. it has been around
since windows 2000. we had to install a newer version of mscomctl.ocx for
win 2000 clients and still need to install it for customers who have not
upgraded. now xp sp2 users are saying we are overwriting their newer
versions of mscomctl.ocx.

it seems like we are checking the version, but.....
it does not seem like xp would allow us to overwrite an older ocx in the
windows directory?
would this be possible?
i would think xp would stop an older ocx from writing over a nwer one?

thanks for any help

The Windows Common Controls Mscomctl.ocx or Comctl32.ocx may cause
your application or the Visual Basic 6 IDE to unexpectedly quit, or you may
receive a "Divide By Zero" error message

XP has a built-in feature which protects the "core" files. If it detects a
core file change/removal, XP will restore it with the one it has registered
as the good one.

thank you.

how does it know what is a good one?
when we install we actually register the ocx. Through regsvr32.exe.
so would windows consider it a good ocx at that point?
i would think it just wouldn't let us overwrite a newer version.

thanks
