Delphi XE - [DCC Error] : E2004 Identifier redeclared: 'System'

Question

I do not understand why this error occurs...Is this a bug in XE, or is something wrong in the IDE settings?

Answer 1

The System unit is automatically used by all other units in a Delphi program. So you cannot use it again. Simply remove System from your uses clause.

The documentation states:

The System unit and the SysInit unit are used automatically by every application and cannot be listed explicitly in the uses clause.
