teeChart and error load package

If you get errors "Can't  load package ...
A device attached to the system is not functioning",
check registry HKEY_USERS\.Default\SOFTWARE\
Borland\Delphi\4.0\DisabledPackages
and delete parameters which should be installed.

Probably problem in that that the same packages teeChart
have a different option value in the registry and simultaneously get
both in DisabledPackages and in KnownPackages
