Development of HKEY Property Editor is frozen.
The property editor behaves erratically. In some Delphi installations it works as expected but in others the object inspector does not recognise it. The reason for this is unclear. Because of this the editor has been deprecated.
You are strongly advised not to install this property editor.
Anyone who wants to have a go at fixing the editor is welcome to take over development. The code is open source and uses the Mozilla Public License v2.0.
There is no support available for HKEY Property Editor. Please do not report any bugs or request new features.
