We have several icons in the NAL which all as dependency bundle have "Firefox install".
I already placed the bundle install under the launch-tab of the parent bundle, and put a "registry key exist" requirement-setting, which checks if the uninstall key of Firefox is present, and is set to "no", to not run the install every time the parent icon is being clicked.
However, if I remove the registry key manually, and click the icon where the install bundle is assigned, the install bundle is not being installed.

I'd like to have just one Firefox install-bundle, so I only have to update the one bundle, and I don't have to update several bundles.
We (still do) use Zenworks 7, and here we do use this feature, and it works flawlessly.

Is there a way to do this without too much of a hassle?
