Delphi 2007 - error running on 64-bit Windows
Delphi 2007 is not new although it is the last non-unicode release of Delphi hence it is used frequently to maintain legacy code base.
And it has bugs. Some of them can be fixed by VCLFixPack and affect only compiled binaries.
Some are related to IDE and neither CnPack nor GExperts IDE extensions can fix them.
