Delete and Uninstall

Hi.

We have the problem, that we have old entries, which aren’t valid any more (the machines don’t exist any more).
I used “Delete and uninstall” from the kontext menu and now it says " Uninstall running" - but nothing happens (the managing console can not handle missing hardware).

How can I manually remove obsolete entries without uninstalling!?

Regards

Sorry, problem has been settled:
the contect menu isn’t completely grayed out any more but now the “Delete and Uninnstall” can be klicked again…
