Uninstallable add-in

[Mark]

Hi,

I am interested in creating an add-in for Microsoft Outlook which should be
deployed to all computers in our organization. However, we want to prevent
users from uninstalling the addin. How can I deploy an add-in with such
restriction?

Thanks,

Mark

If it's deployed as an administrative addin registered in HKLM and you're
using an OS that restricts things such as Vista or Win7 then unless the user
has admin permissions they won't be able to install or uninstall it.

Hi Mark,

We use a product called Tarma (Expert & Professional). You can install the
product and make sure that the uninstall is not listed within the control
panel. I highly recommend this installer!

If you are installing this on a network and are thinking of doing an Active
Directory push. Then you can create an MSI with the Tarma expert installer
that essentially executes the tarma professional installer. We have done
this several times for medium to large sized businesses.

We use the tarma installer when we install our child protection software and
it is very hard to uninstall our product without being privy to uninstall
instructions (plus you can password protect the uninstall).

Regards,
Tom

Hey, thanks for the tip

That looks fine to prevent the user from completely deinstalling the add in,
but I think the user can still disable it inside an office as far as I know
(might be wrong)
