Vcl.ExtDlgs was compiled with a different version of Vcl.Dialogs.TOpenDialog?

HI

Compiling the first project in delphi 12, I get this error

[dcc32 Fatal Error] : F2051 Unit Vcl.ExtDlgs was compiled with a different version of Vcl.Dialogs.TOpenDialog

But  Vcl.Dialogs.TOpenDialog.pas does NOT EXISTS?

 

dir \Vcl.Dialogs.TOpenDialog.pas /s
 Volume in drive C is Acer
 Volume Serial Number is A295-B72F
File Not Found

 What am I missing?

TOpenDialog is the class. Vcl.Dialogs.pas is the file containing that class

You want to look for Vcl.ExtDlgs.* and Vcl.Dialogs.*

 

Do you recall modifying either Vcl.ExtDlgs.pas or Vcl.Dialogs.pas?  Do you have multiple versions of Delphi installed? Are your library and search paths set correctly?

 

The compiler is finding versions of those two units that are not compatible. This primarily occurs when the interface section of one unit does not match the interface that the other unit was compiled against.
