I'm working on an asp.net project where we decided that we needed an ActiveX
control to handle the UI for one particularly complicated peice of
functionality.  The control was developed in VB6 and packaged in a CAB file.
We've embedded the control in a web page and tried loading the it on a
number of computers in the office (all running XP) and it seems to load
properly on some computers but not others.  I need to find out why it is not
loading on these computers and fix the problem.  When the conrol does not
work, there is no error message, just the familiar empty box with a red X in
the top left corner.

We have done a lot of testing on one particular computer where the control
does not load.  We have added the test page to the "Trusted sites" list in
IE and ensured that the security setting for trusted sites was "low".  Weve
tried signed and unsigned versions of the control.  with the unsigned
version we get the standard security warning. The control  does not seem to
get put into the "C:\WINDOWS\Downloaded Program Files" folder, and when it
seems to try to re-install the control every time i refresh the page (i.e. i
get the security warning each time and then IE apears to be downloading for
a few seconds)

I've hunted around for documentation on how to fix this this but i havent
been able to find anything.  I'm stumped as to what other steps to even take
to further diagnose the problem.  Any help or insight i could get for this
problem would be appreciated.

Thanks.
