Neil, thanks for your reply. Our servers are Windows 2003 SP1 PS 4 Rollup 1.
I can see how your solution would work. However, it's way too much work for
what is at the moment a non-critical request which may just fade away.

You don't mention the OS version of your Citrix servers. I haven't done
any checking to see if there's much change in this for 2003 server, or
whether the reg keys are overridden by HKCU settings... but here's what
I had to do when deploying apps that used Active X controls (on NT4 TSE,
and Windows 2000 TS).
I initially set the registry values
HKLM\Software\Microsoft\Windows\CurrentVersion\InternetSettings\ActiveXC
ache to be H:\Windows\Downloaded Program Files. I made sure that the
admin user I was running as had such a folder available (I probably used
subst whilst logged in as an admin user). I then ran the app, and
accessed the portion that used the ActiveX control. This did all the
HKCR\CLSID stuff for creating the objects on the system. It also copied
/ cached the actual ActiveX object files to this folder. I saved these
controls to a central location, and using a login script for the user,
ensure that the same path (H:\Windows\Downloaded Program Files) was
valid and existed for each user - then the control files were copied to
their local folder.
This was a signed ActiveX control, so I created the digital signature in
users profile by writing the value in a login script (mandatory
profiles).
So when the user ran the app and accessed the bits using the ActiveX
control, their profile had already been pre-populated with the digital
cert signing the control, so accepted it. The OS new the control was
already installed (due to the HKCR\CLSID stuff that had been created
when I ran the app using an admin user), and the control files were in a
folder that was writable by the user if they were updated.
This meant they could use ActiveX for the app, but not install ActiveX
controls generally. I had control over the version of the app, too -
because I had to pre-empt the digital cert using a login script
(mandatory profiles).
I suspect where you might want to start is ensuring that the HKLM
registry value above is set to an area that will exist for each user,
and is writable (that latter part seemed to be significant, from memory,
even if the control files were already present), before installing the
control. Otherwise you're like going to have to set it anyway, and
search HKCR\CLSID and probably change some values in InprocServer32 for
the control(s) so that it points to the ActiveX cache area you want to
use for your users.
There may be other / better ways of doing this now I don't currently
have to deploy any apps using ActiveX controls any more, but that's how
I went about it then, going back a few OS versions, and bearing in mind
I always used mandatory profiles.
Neil
