Remove emply component tabs

I installed some demo packages into Delphi XE.

I want to delete these.  I went to "Components/Install Packages" and, after selecting the package, clicked the "remove" button.

However, empty tabs for these components are still available.  How can I get rid of this?

I have tried uninstalling and reinstalling delphi but without success.

Many thanks for your help.

Try to locate in registry keys:

Known IDE Packages
... and ...
Known Packages

under Embarcadero key and delete problematic package. If you don't succedd
then delete whole Embarcadero key from registry and install delphi again.
