Our application is written in VB 6.0. Our client installed our application
on several machines. On all Win9x machines it works fine, but on NT 4.0
machines they have 2 problems:

1. They get error "Run-time error '429': You do not have an appropriate
license to use this functionality". This is when it tries to bring up a form
that has a rich text control in it (Richtx32.ocx).

2. On another part of the system when it suppose to open a common dialog box
(Comdlg32.ocx), it never opens the common dialog box, it just skips it
without opening it.

Our installation copies Richtx32.ocx and Comdlg32.ocx if our version is
newer than the version on their machines and our installation also register
those controls. How can I fix this problem? Thank you.
